WiBeee: Your consumptions in the palm of your hand


An efficiency expert always with you

In the current era of information, energy consumers must be able to obtain data on their electrical consumption, in order to be able to take action to improve the energy efficiency of their installations and to make substantial savings in their electricity bill.

Likewise, due to the difficulty of obtaining consumption data from the installed electronic meters, users do not have the chance to react before receiving their electricity bill.

To help us therefore understand how we consume energy and how to reduce consumption, CIRCUTOR is launching one of the most innovative products on the market in recent years: Wibeee.



What is Wibeee?

Wibeee is a consumption analyzer (single-phase or three-phase), which uses a Wi-Fi wireless connection for obtaining electrical data to facilitate decision-making when it comes to understanding the use of electrical energy.

The unit can be attached to any part of the installation, which helps you to detect any problematic points where energy is not being used efficiently, thus making a significant contribution to the reduction of energy consumption via the remote activation of alarms when the desired limits are surpassed.

In short, Wibeee is the ideal tool to make your electrical installations efficient, for finally taking control and deciding where to spend your money. Finally, a device with personality. Wibeee displays everything you couldn't see before.


Once connected via Wi-Fi, you can immediately access the instantaneous data using your smartphone, tablet or PC, which allows you to view your electrical consumption in real time. In addition, Wibeee also sends all of the data to a server in the cloud server so that you can view and compare the various past consumption logs in a user-friendly manner.

With Wibeee you will no longer get a surprise with your electricity bill, learning to manage your consumption in a simple way.

Wibeee. Cable-free. Wireless system

  Wibeee. Accurate measurement
The entire system has been designed to monitor information over wireless communications networks. Nothing can come between Wibeee and you.  

You may be thinking that such a simple installation could result in loss of measurement accuracy, but that is not the case. Wibeee has a minimal error percentage and so is able to maintain the measuring guarantee that CIRCUTOR units have always been known for.


How will it help you?

Wibeee shows you the instantaneous and past electrical consumption data using any smartphone, tablet or PC, with the help of its integrated web server or via the free Wibeee Circutor app, available for iOS or Android. In other words, it enables a direct Wi-Fi connection so that you can view your data.

It is also possible to configure the consumption analyzer so that it sends the data automatically to a cloud server in order to log the data. With Wibeee connected to the Internet, you can view instantaneous and past data using your smartphone or via alerts configured by your smartphone. Connect to the web platform to consult your data, carry out analyses, configure your user profile, etc. The logs of the analyzer in the cloud are also fully integrable with any platform on the market.

Wibeee is therefore the ideal tool for making your electrical installation efficient, controlling and showing your savings and helping you to take the right decisions in terms of managing energy efficiency.

Consumption control, electrical savings


Comparisons are not tedious

Wibeee. Consumption control, electrical savings

  Wibeee. Comparisons are not tedious
Wibeee collects the necessary data on electricity consumption and helps you interpret them, know your consumption profile and save on your energy bill.  

Wibeee lets you analyse your installation(s) by making comparisons between more than one Wibeee or between different periods of time, if you wish. It lets you confirm that the actions you take for energy savings are getting their expected results.


It couldn't be easier to install, it's as simple as putting a magnet on your fridge!

The installation of any electrical metering unit can be a complicated task as it requires wiring space and time. Wibeee is extremely easy to install: in ten seconds it's done.

Our technology, which is attached via a clip, is based on the patented system DINZERO and consists of attaching the unit easily to the cable or simply to the upper part of an MCB (miniature circuit breaker). Once switched on, it will begin to convert the measured parameters into information that can be sent via a wireless connection.

How can you interact with Wibeee?

Wibeee logs the electrical parameters of the installation so that you can view them from wherever you want: from the computer in your office, via smartphone from the café on the corner or from your tablet lying on your sofa at home. Wibeee can also be integrated with the other devices that are compatible with the PowerStudio SCADA system.

The data will be logged in CIRCUTOR's cloud server or can be sent to your own local server, giving you the option of choosing the system that best meets your needs. Once the data has been logged, you can then access it via the following means:

The Wibeee Circutor app is used to register all of your Wibeee units to be installed, as well as to monitor consumption and other electrical variables in real time, or to view past data logs that the units have been logging in the cloud.

Wibeee Circutor allows you to connect your smartphone or tablet to the SSID network of each Wibeee, which will display some simple graphical steps showing you how to install the units, add them to groups and subsequently monitor them.


Once the unit has been configured, you can control it from any point in the installation, with no effort whatsoever, being able to check the status of your installation, past consumption and alerts such as excessive consumption of reactive energy, tripping of protection elements or faults in the capacitor bank.

Once you have installed the Wibeee consumption analyzer, it will begin to send data to the cloud server. This data will be stored there so that you can view it at any time without needing to be connected to your own unit. You can also configure the unit via the web portal, generate alarms or compare consumption data with other Wibeee analyzers that you have installed.

Wibeee CIRCUTOR Portal

Once registered on the platform, you can access the various screens for managing and comparing your consumption data.

Individual management

The web platform shows you a general summary of consumption (energy, CO2 emissions and cost in euros), with the option of creating an alarm for excessive consumption.

You can also view incremental graphics of active power, cost and emissions (as well as exterior temperature from an external server) for any period, as well as being able to export the data in Excel format and view a summary of costs for the selected period.

General summary of consumption with Wibeee

From the web portal you can also view data logs for electrical variables such as: voltage, current, apparent power, active power, reactive power, active energy, reactive energy, frequency and power factor in any period.

View data logs for electrical variables with Wibeee


Once the different Wibeees have been registered, you can make comparisons between them to see which is the most efficient and what level of consumption is being logged by each one. This feature is incredibly useful in installations with a similar topology as the one that manages energy the best can serve as an example for the rest, helping to change bad usage habits.

In addition, if you install a number of Wibeee analyzers in one installation, you can segment the consumption data by use (lighting, air conditioning, power etc.) and check how and when you consume energy.

For many years now, power factor correction has been one of the first steps to improving the energy efficiency of installations. Since their beginnings, compensation techniques have grown and developed over the years, adapting to new needs (basically the types of loads that must be compensated) and to new technologies that have become available.

At first, the most common compensation technique was to use capacitor banks with contactor operation. This compensation system is optimal for balanced systems and to compensate loads with connection and disconnection rates that are not too fast, on the order of seconds, and it is currently the most common system in most installations despite increasing numbers of unbalanced installations.

The passage of time and the growing use of more dynamic loads in many installations has led to the emergence of a new technique: the use of static contactors (solid-state relays or thyristors) to operate the capacitors in a capacitor bank. This technique has a set of important advantages over compensation with contactor operation:

  • Response speed: the use of thyristors enables compensation in installations with highly fluctuating load variations (in cycles, on the order of ms), making it the optimal solution for cosφ correction of very fast loads. The paradigmatic case would be the compensation of welds, although lifts, freight elevators, compressors, etc. would also be on the list of likely loads.
  • Elimination of mechanical wear: contactors have a limited mechanical life, which incurs the need for regular maintenance to ensure the capacitor bank is functioning properly. The use of thyristor operation eliminates this need, extending the useful life of the capacitor bank assembly and reducing maintenance costs.
  • Less noise: the use of electronics during contactor operation eliminates mechanical noises generated by the contactors, which can become an annoyance in service installations.
  • Elimination of connection transients: the use of zero switching control boards ensures the elimination of transients when the capacitor connects, giving it a longer useful life and eliminating disturbances on the electrical network.

In the early days of this new technology its main drawback was its high price, which meant that investing in this type of unit necessitated long repayment periods for most companies, making it difficult to justify the expenditure, even more so if compared to traditional compensation with contactors.

FO OPTIM EMS-C 250x250

CIRCUTOR was a pioneer in developing the technology used in static capacitor banks and has included them in its catalogue for more than 20 years, making the company a leader in this technique within the electricity market. In recent times, significant R&D efforts have been made to adapt the new emerging technologies to this compensation technique, developing a new range of static capacitor banks that drastically reduce the price difference between the two compensation systems (contactors / thyristors), thus eliminating the main obstacle to choosing a static capacitor bank as a compensation method.

To this end, CIRCUTOR has launched the new range of EMS-C static capacitor banks which are ideal for industrial applications, such as arc welding, compressor start-up, cranes and hoists. But they are also suitable for the service sectors, such as compensating lifts in communities of residents, given that the traditional contactor technique does not compensate them well due to their quick input and output rate.

Thanks to minimising the cost difference between classic compensation with contactors and advanced static compensation, CIRCUTOR has turned the choice of a static capacitor bank from a technical whim to a tangible reality within the reach of all budgets.

数据中心如何提高电能效率 (DPCs)


The importance of knowing the PUE. Managing effective energy use

We can calculate the energy efficiency of any production system by comparing the useful energy with the total energy needed by the system. With this information and knowing where the inefficiencies are, we can achieve substantial savings and more environmentally friendly operations.

As a practical example, an average data processing centre with installed power of 100 kW can achieve savings of €8,000 to -€16,000 in the electricity bill as a result of improved energy efficiency. To do so, it is as important to detect the points of consumption as it is to assess the corrective measures.

The energy factor is so critical in data processing centres that it has its own indicator: PUE or Power Usage Effectiveness, defined by a standard issued by The Green Grid, a global environmental agency comprised of over 175 internationally renowned companies.

The European Commission also has a code of conduct for reducing the impact of data centres' growing energy consumption.

It periodically publishes best practices for data processing centres, most recently in 2013.


These centres have a peculiar profile due to their uninterrupted working hours. Because of the great importance of service continuity when powering servers, computers and communications, they have three main groups of units for their exclusive use:

  • Energy supply and control units (electricity and other sources, such as diesel oil, gas, etc.) essential for the functioning of these continuous operation units. This group includes supply connections and switchboards, lighting and refrigeration systems, air conditioning of the corresponding rooms, etc.
  • One or several units to supply power computer equipment (IT), comprised of UPS (Uninterruptible Power Supply) units .
  • The distribution panels and systems for this energy to power the computer equipment.

Broadly speaking, we can say that of the 100% total energy consumed in a DPC, 60% corresponds to the infrastructure's electrical consumption and the remaining 40% to refrigeration systems.

So we can undoubtedly see the need for coefficients (PUE) that make it possible to prepare comparative studies aimed at determining actions for optimising the energy consumption of these centres.

Calculation guidelines

As we have already seen, we normally use the standard issued by The Green Grid to calculate the parameters for DPC efficiency. We will distinguish two key indicators:

1. PUE: Power Usage Effectiveness, calculated with the formula:


2. DCE: Data Centre Efficiency, calculated as a percentage with the formula:


In addition, the Environmental Protection Agency of the United States (EPA) provides the following PUE values as a reference:

  • Historic 2.0
  • Current trend 1.9
  • Optimised operations 1.7
  • Best practices 1.3
  • State-of-the-art 1.2

Companies like Google have gotten the average PUE of their DPCs down to 1.22, and sometimes as low as 1.15.

In the historic frame of reference (PUE 2.0), typical consumption for different DPC elements is:


Therefore, one of the keys to the success of an energy improvement project is measuring the consumption of each unit type in order to be able to recognise the most affordable areas of improvement.

There are three general measurement levels* shown in the table below, with measuring points that correspond to the indicators in the diagram also shown below, with energy measured in kWh. A 12-month cycle is taken as a comparative reference for all levels.

There is also a Level 0, which only includes power measurements (kW), measuring the general demand of the installation and that of the UPS output.

measuring the general demand


CIRCUTOR with its decades of experience in energy efficiency, solutions, offers a wide range of products that facilitate continuous data gathering for controlling PUE and DCE, UPS unit performance, electric energy management and DPC maintenance. These include energy meters, power analyzers, ultra-immunised earth leakage protection, harmonic filtering systems, PowerStudio Scada management software and power factor correction systems.

CIRCUTOR’s Solution with the SCADA system

For the study, two implementation phases and a third study phase are required:

  1. Measurement: with the addition of CVM power analyzer units, with their corresponding current transformers, equipped with RS485 serial communications to measure circulating energy.
  2. Analysis: installing the PowerStudio Scada application, calculating and viewing the resulting values and running the corresponding reports.
  3. Improvements: analysing the collected data lets us see which units are consuming.


The application features:

A start screen in single-line diagram format (Fig.1) with data corresponding to all the concurrent energy types (converted to KWh).   single-line diagram
A second summary screen (Fig.2) with performance calculations (Fig.3), enabling you to create and display reports with results for different periods (daily, weekly, monthly and yearly).    performance calculations

By way of example, here are the screens displayed when installing CVM analyzers and programming a specific Scada application.

On the first one you can see the installation diagram and unit connections; on the second one you can see the resulting data online for a single DPC; and on the third one is a weekly Level 1 report with continuous measuring frequency.

For the study, two implementation phases are required:

  1. Addition of CVM power analyzer units with their corresponding current transformers, equipped with RS485 serial communications to measure circulating energy.
  2. Addition of an EDS energy controller with storage and data processing functions and its built-in programming, along with a local display screen.

By way of example, here is the communication topology displayed when installing CVM analyzers, the EDS energy controller and the local display screen.

How to improve the efficiency of a data processing centre

To improve the efficiency of a data processing centre, we must follow measuring and analysis by implementing improvement actions. There are actions that do not require any investment, such as reducing the contracted power to save on direct costs, and other actions that do require investment, such as replacing units with more efficient ones.

To organise these improvement actions you can prioritise them in accordance with the efficiency that can be achieved with each one. This prioritisation is calculated by comparing the improvement obtained with the investment required to make the improvement.

Action priority   

Pa: Action priority
CEa: Current energy consumption
CEm: Energy consumption with the new measure.
Investment: investment needed to achieve the savings

Performing this calculation for each possible improvement action helps us prepare a list of actions and sort them from highest to lowest priority.

Possible short-term measures include:

  • Analysing usage patterns for the environments where they have been deployed.
    • Calculating the minimum server group sizes to maintain service levels.
    • Switching off unused capacity, as long as proper availability is maintained.
  • Virtualisation and consolidation
  • Replacing hardware
    • Virtualising test environments.
    • Replacing obsolete hardware.
  • Changes in room management
    • Correct control and adjustment of room temperature.
  • Changes to the refrigeration infrastructure.
    • New efficient refrigeration machinery.
    • Hot aisle/cold aisle layout.
    • Elimination of "gaps" in the racks.
    • Future: use of outside air.
  • Lighting optimisation

For a more thorough list of Data Centre improvements, see the "2013 Best Practices issued by the European Commission's Renewable Energies Unit."


DPCs (Data Processing Centres) are major consumers of electrical energy and their consumption can be divided in useful energy for computer equipment and the additional energy necessary for their smooth functioning. This energy consumption is so critical that it has its own indicator: PUE (Power Usage Effectiveness).

In DPCs with non-optimised PUEs, this additional energy can account for up to 50% of the total energy, giving us good room for improvement. According to minimum availability requirements and the options for investment in improvements, savings of up to 20% of the total energy consumed can be achieved (or between €8,000- €16,000 a year in an average 100 kW DPC).

As we have seen in this article, it is possible to study and measure possible improvements to data processing centres. The key phases are installing energy measuring units, analysing the data gathered and making decisions based on that analysis.

CIRCUTOR, with its decades of experience in energy efficiency solutions, offers a wide range of products that facilitate continuous data gathering for control, maintenance and energy efficiency management of DPCs.

The perfect formula to improve the sustainability of companies

The agreement signed in February 2014 between FEC (Future Energy Consulting Services GmbH) and CIRCUTOR to promote and develop activities related to marketing energy efficiency and solar energy solutions has begun to see results.

This first year of working together has resulted in the development of three projects that deliver the perfect combination of environmental sustainability, economic viability and social outreach for companies as varied as a car dealership and a vegetable processing and packing plant in Southern Spain.

The FEC group includes the development company PROCONSULT and the SOLAREC engineering company specialised in implementing solar energy systems. They have both worked with CIRCUTOR on the design, construction and start-up of the first three projects of a long list that will be refined in the upcoming months.

PROCONSULT's solutions for companies come together under the term SUN TOWER, which encapsulates the concepts of:

  1. Improved building energy efficiency through the implementation of an energy monitoring application with POWER STUDIO SCADA.
  2. Harnessing the building's potential for energy self-production through the installation of photovoltaic solutions like the SUN TOWER solar tracker, rooftop solar systems and CIRCUTOR's PVing Park photovoltaic canopies.
  3. Adapting the building for the arrival of electric vehicles through the installation of CIRCUTOR's RVE2-P charging points in a solar parking area.

The solution is backed by a guarantee to offer each client the best solution adapted to their consumption needs and available spaces. Mature solutions, proven technology and suppliers with financing available. This means that projects can be undertaken by companies with confidence that resulting savings will offset the investment made and that financing is guaranteed.

Energy costs currently account for a high percentage of company spending, with the added uncertainty that future instability could jeopardise competitiveness. The strength of these solutions is that they allow the building to use sunlight to generate between 30 and 50% of the energy required on-site and reduce energy requirements to a minimum with consumption monitoring that makes it possible to define actions to be implemented and quantify their results.

PV system can add around  50% the energy demand
PV system can add around
50% the energy demand

All these projects have been formalised under the heading of photovoltaic energy installations connected to the grid with zero injection of surplus energy. This formula significantly eases the administrative requirements of solar installations designed for the self-sufficiency of buildings. The system aims to reduce internal electricity consumption, achieve energy independence, and generate energy locally, not for injection into the distribution lines.

The solar production is regulated through the Dynamic Power Controller (CDP) designed by CIRCUTOR. This device sends a power modulation order to the solar system inverters so that they adapt the generated power to a maximum value that is always less than the instantaneous power demanded by the loads in real time.

The fact that self-consumption photovoltaic systems produce part of the energy required by buildings and do not inject surpluses into the grid allows government to assign them an energy savings role, facilitating their processing. Likewise, having no grid injection frees these systems from maximum installable power restrictions based on the discharge capacity of the distribution lines.

The term SUN TOWER broadly encompasses the implementation of PowerStudioScada energy management software, solar tracker systems, rooftop systems and CIRCUTOR's PVing Park photovoltaic canopies, as well as RVE2-P quick charging points for electric vehicles.

Solar photovoltaic systems for selfconsumption with zero injection into the grid are supported by a growing number of governments that provide for legal installations in a simple, quick and economical way without the need for prior approval processes with the utility companies.

The integration of all the activities from the various projects into a single platform through the POWER STUDIO SCADA monitoring and supervision application allows you to not only quantify the solar production of each of the systems, but also tracks the evolving consumption of each productive section of a company as well as the impact of the different energy savings actions that have been implemented.

The SCADA application enables SOLAREC to perform corrective and preventive maintenance in order to guarantee the results of each of the projects as well as design future energy strategies for each user.

By performing simulations to generate the energy bill and calculate the impact of the savings provided by solar production, you can verify the profitability of investments as well as the specific energy costs of each business process in every industry. The design and implementation of the POWER STUDIO application as well as the electrical installations required for these projects have been carried out by CIRCUTOR's expert engineering and installations company, Aseprel, SL (www.aseprel.es)

The installation of the RVE2-P electric vehicle charging points in the projects not only conveys an image of modernity and environmental commitment to employees and customers of companies, but also serves to adapt the infrastructure to new transitional energy regulations centred on mobility, like the recently-approved ITC-BT-52 of the Low Voltage Electrotechnical Regulation.

The 246 kW of rated power installed in the three completed projects have an annual production potential of nearly 400,000 kWh. This would mean approximate energy savings of €80,000/year and a reduction of 90 tonnes of greenhouse gas emissions into the atmosphere each year. Moreover, the three QUICK charging points for electric vehicles will provide the basis for a provincial infrastructure that will enable the development of these vehicles, resulting in greater cost reductions and emissions in the years to come.

These projects have undoubtedly positioned the companies of the FEC Services group at the forefront of solar energy technology in buildings and as a sector leader in Southern Spain. This has paved the way for the group to win more projects and expand its activity to other areas with identical needs and great potential for savings.

Based on the experience gained in these first projects, now in operation, FEC Services and CIRCUTOR are working to adapt this partnership scheme to Latin American countries where there is a great need to provide solutions in energy efficiency, self-consumption of solar energy and the integration of electric mobility. The first projects are underway in Mexico and Chile.

近二十年来CIRCUTOR一直采用气体填充技术,与其他最先进的技术一起,使电容器成为市面上称之为增强型的电容器。电容器长时间可达1.8倍额定电流,达到2.5倍额定电流,并且峰值电流最高可达400倍额定电流。IEC-60831的D等级,低压电容器的生产标准,设置最大工作温度值在 55ºC,但CIRCUTOR增强型电容器的强度支持电容器在极限温度环境下工作,瞬时温度支持达到65ºC,另一个重要的特性是支持150,000小时使用寿命。所有的这些特性使得CIRCUTOR增强型电容器有很高的抗性和持久性。

With CIRCUTOR Heavy Duty, the key material is metallized polypropylene, which is always of European origin with the very highest performance features.




  • 与其他相同容量的电容器相比,增强型电容器同时节省了运费和所配的电池的成本,更好的节约了成本,最终用户与整个供应链共同达到了双赢的结果。
  • 提高了安全性,归功于更高效的内压安全阀保护系统。在没有液体溶剂(油)或固态填充物(热固性树脂)时,故障产生的情况下,电容器内部气体扩散直接作用于内压安全阀保护。
  • 无泄漏同时支持多种安装方案,适用于不同类型的柜体,最优化适用于每一位用户的最终解决方案。
  • 注重环保,因为电容器注入了无害的惰性气体,不含油性或其他有泄露风险的填充物。

CIRCUTOR增强型电容器承诺达到高水准的特性,最少的维护,保持温度达到150000小时的工作寿命。CIRCUTOR Heavy Duty capacitors saturated with inert gas (DRY technology) are very safe


增强型电容器除了填充惰性气体以外,另一个优势是全金属化自愈的能力(figure 1),防止了电介质击穿后的漏电。这提高了在任何电网下的过压,工作温度过高,以及电网中需要补偿的谐波电流,甚至过多的投切操作次数的的耐受能力。Self-healing process of the metalized polypropylene

和其他任何材料一样,随着时间的推移,聚丙烯会发生化学改变。这会影响到电容器的电力因数。正因如此,电容器应该装备相应的保护系统,这样当有必要时,可以将其断开以避免影响到相邻元器件(电容器,投切设备,电抗器等)。在这方面,CIRCUTOR增强型电容器配备了泄压保护系统,当电容器内部压强高于506 hPa时,约(0.5 bar),系统将会启动,会将电容器从电网中断开,如 figure 2所示。Figure.2  The CIRCUTOR Heavy Duty capacitors have an overpressure protection system which is activated in case of any increase in internal pressure, disconnecting the capacitor from the network.

  1. 一旦电容芯被放置在铝管中,必须确保完全排除了这些组成部分中的任何可能存在的湿度,所以每只电容器都在真空环境下经历了一个漫长的真空处理程序。这是非常有必要的用于确保没有任何的湿度和氧气残存在电容器内部,可以有效的防止聚丙烯膜金属部分的氧化。这一防止氧化措施同时可避免电容器的快速衰减从而降低了了电介质损耗。减少了内部放电并提高了其整个工作寿命期间的容量。
  2. 在真空处理过后,电容器内部将会充满 N2 (氮气)以及He4(伴有4个原子质量的氦气同位素,其中有一个非常低的密度,是无色无臭无味的自然元素)的混合气体。再一次置于真空条件下,直到电容器内部压力微高于1013 hPa (1atm)。图片显示这一填充过程。
  3. 在图中可以看出,在填充和密封电容器过程中,电容罐顶盖已经装有一套端子用于将电容器连接到电网。这些端子内部已经装备了放电电阻,用于电容器放电,从电网中断开后 3分钟内达到小于75 (如图所示),符合应用标准IEC 60831-1所列明的。
  4. 在生产过程的最后将进行基本的性能测试以保证每只电容器的质量与性能:检查密封过程以保证内部气体没有泄露。如果检测到有任何泄露存在,这只电容器将会从生产过程中被取出。.

New CEM series of multifunction energy meters for DIN rail connection

In an increasingly globalized world it is essential to manage efficiently the electrical consumption. In addition, the steady increase in the price of energy creates to the users the need to find new formulas to manage their installations.

The new CIRCUTOR's CEM series of multifunction energy meters provides all the essential information about the different consumption habits of an installation, helping to save money, resources and improving the installation's electrical energy efficiency.

The information is the key for an efficient management

The information is the key for an efficient management

Why install a CEM meter?

The objective of the new modular CEM meters is to allow the user to understand the electrical installation behavior by recording real energy patterns in order to take correct decisions to reduce and manage its electrical consumption. Thus, the user gets all the relevant information about how, when and where the energy is consumed. With all that information, it is possible to have all the billing data before receiving the utility's official bill, allowing the user to share out the costs with the different areas in the installation.

The task of identifying the individual consumptions, in one installation, is an almost impossible exercise if sectorized measurements are not taken. Therefore, to allocate costs to processes, devices or areas, it is completely necessary to implement a solution able to report detailed information about the electrical consumption by subdivisions and/or individually. In addition, CEM meters register the energy monetary cost (Euro, Dollars,..) and kgCO2 emissions for each tariff.

As an added value, it's reduced space and easy installation on DIN rail avoids high investments in modifying the current installation. This makes the new CEM's ideal to be installed in any switchboard or existing machinery.

The importance of the MID approval (EN 50470)

The new CEM energy meters are certified according to the European Directive MID (EN 50470). This allows the meters to be used for economic transactions (internal energy invoicing).

The EN 50470 standard declares the design and manufacturing process control by an external laboratory, ensuring the meters quality and transmitting the confidence to the different end users.


The new modular CEM meters are designed to be installed in any sector or application, always offering a wide range of advantages to the end user. Summarizing, three different areas of use can be defined:

  • Tertiary sector: Is common to find installations such as shopping malls, hotels, campsites, offices, airports or marinas where there is installed a single official utility meter which measures the total consumption of the installation. To allocate the real energy cost to the end users some formulas can be used but the most correct action would be to measure the real consumption, with high accuracy and individually.

Moreover, its reduced space with DIN rail connection makes its installation fast and easy in the existing switchboards.


Individual measurements allow a correct allocation of costs

  • Industrial sector: All industrial installations have an official billing meter installed on the main to measure and register the total energy consumption. However, this fact creates an ignorance of where, when and how this energy is consumed.

Registering the electrical consumption, the manager will be able to make the right decisions while connecting the different loads or starting processes, preventing simultaneous consumptions and maximum demand penalties. Moreover, the manager will have enough information to select the installation's most suitable electrical tariff.

As additional features, CEM meters register the energy cost (Euro, Dollar,...) and kgCO2 emissions for each tariff being key factors for understanding and improving the energy efficiency of the installation. Thus, by means of rigorous measurements, the operational manufacturing costs (OpEx) will improve.

The measurement requires precise knowledge, individually or sectorized, of each productive process

or sectorized, of each productive process

  • Condominium: There are some buildings where the neighbors share between them the total electricity bill without any control. In these cases, there is a meter installed on the main and the total consumption is paid by dividing the cost between the different tenants. Without an individualized measurement the distribution of costs may not be equal because it depends on the use of each tenant.

Installing the new modular CEM meters, the manager avoids possible complaints from the tenants. Therefore, installing individual meters together with the PowerStudio Scada software, the manager will be able to invoice customized bills to each tenant, even before receiving the official utility bill for the entire building.

Individual measurements transmit confidence to the different tenants

The benefits for each sector can be summarized in the following table:

  • Equitable energy cost allocation through individualized measurements (processes/tenants).
  • Possibility to communicate the CEM meters with PowerStudio Scada to invoice customized bills to each tenant.
  • Reduced space in DIN rail connection with easy and fast installation.
  • MID approval (EN 50470) ensuring the safety and meter accuracy
  • Improvement on operational costs due to the measuring and monitoring of real energy data.
  • Operational costs registration via Modbus/RTU by using Scada software.
  • Displays the energy costs (Euro, Dollar,..) and kgCO2 emissions on each tariff.
  • Prevents simultaneous consumptions and maximum demand penalties.
  • Helps to select the most suitable electrical tariff.
  • Reduced space in DIN rail connection with easy and fast installation

CEM meters with OSC communications

In order to perform the different energy consumption analysis, CIRCUTOR launches the new CEM series of multifunction energy meters for DIN rail connection with OSC communication system. The new range consists of single (CEM-C10) and three phase direct (CEM-C20) and indirect (CEM-C30) meters. All the meters have a single pulse output to send pulses in relation to the consumed or generated energy.

To provide communications to the system it is as easy as coupling an additional CEM-M module which communicates directly with a CEM meter through OSC system. This system consists of an optical window that allows optical communications between the meter and the CEM-M module without the need of any extra wiring. Furthermore, the CEM-M module has a wired RS-485 output to send the meter's information to our PowerStudio Scada software via Modbus/RTU to register and monitor all the relevant data such as energy consumption, voltage, current, power, power factor and frequency.

The solution: New CEM multifunction energy meters

The new range of modular CEM meters allows obtaining all the relevant information about the different consumption habits of an installation, helping to save money, resources and improve the energy efficiency of an installation.

The CEM range consists on single and three phase static meters to measure the Active energy with Class B/1 (EN 50470/IEC 62053-21) and Reactive energy Class 2 (IEC 62053-23) with DIN rail connection. Each one has a 7-digit LCD display with scrolling screens and two buttons (1 sealable) to show all energy variables.

The CEM-M module provides RS-485 communications with Modbus/RTU protocol, connecting through optical interface (OSC) to any CEM-C meter.

A large part of unwanted tripping in an installation is caused by a lack of selectivity coordination between the earth leakage protections. With good installation practices, we can solve a large part of the earth leakage protection tripping.

Selectivity in earth leakage protection must be both horizontal and vertical. In this article, we will deal with the 3 essential rules for vertical selectivity

3 conditions must be met in order to guarantee correct vertical selectivity:

  • Amperometric selectivity
  • Chronometric selectivity
  • Type selectivity

Amperometric selectivity

 Amperometric selectivity


This condition must ensure that the sensitivity value of the earth leakage protection connected upstream (I∆1) is more than double the sensitivity of the protection connected downstream (I∆2).

For example, with an earth leakage protection with a sensitivity of 30 mA (I∆2) we might have a protection of 100 mA (I∆1) or higher upstream.

Only with amperometric selectivity would we meet one of the three conditions, so the selectivity would only be partial.

  Amperometric selectivity

Chronometric selectivity

 Chronometric selectivity


This condition must guarantee that an earth leakage protection connected upstream (t1) does not act before a protection downstream (t2) to avoid any current value.

The response times must be kept below the safety limit times.

We will achieve total selectivity along with amperometric selectivity.

  Chronometric selectivity

Type selectivity

 Type selectivity


To guarantee vertical selectivity, the type of class or earth leakage protection upstream must be the same as or higher than the protection installed downstream.

Due to the ever-larger demand in earth leakage protections in installations, more and more type A and type B protections are required, which makes it necessary to respect the vertical selectivity according to the type installed downstream.

  Type selectivity

Selectivity requirements

With CIRCUTOR's RGU-2, RGU-10, RGU-10B and CBS4 earth leakage protections, we can adapt to the selectivity requirements of any installation. We can therefore easily adapt both to the necessary parameters of sensitivity and time.

Earth leakage protection

With a single earth leakage protection, we are able to protect a single load, a sub-panel or a general supply. All of this added to their ultra-immunity and high performance (prealarm, display and communications), make CIRCUTOR earth leakage protections the ideal option for any installation.
