CVM-A1500A. Supply quality management in industry

Continuity in supply of raw materials and the constant flow of resources to production processes have been crucial in preventing financial losses due to production stoppages. As is well known, in both industry and business, time is money.

Production stoppages bring with them financial losses and in most cases they are down to lack of planning, whether due to a logistics issue, lack of preventive maintenance or many other similar problems. There are numerous obvious and visible causes and also others which are harder to identify.

Poor power supply quality is one of them; you cannot see it and its impact may be as serious as any lack of raw material for your production processes. The technology of the machinery involved in these processes is increasingly sophisticated and delicate while the quality of the voltage waveform is taken for granted in most designs.

Many maintenance managers are called in when a machine stops working properly or just comes to a halt for no apparent reason. From then on the experience of the manager and their team comes into play to spot the fault or to restart the system. It is likely that the system will resume operating without any further incidents, meaning the real problem remains unknown and may crop up again at any time with no apparent cause.

There’s no doubt you are getting swells, dips or interruptions in the power supply, and it may be that the electronic systems’ circuit breakers bring the machinery to a halt to prevent damage which can turn out to be very expensive.

Protecting your system against these kinds of problems may also call for significant investment, yet everything depends on how often you have these problems and the impact they have on your operations.

An initial and much more affordable measure is installing a device which can detect and log those problems. With the information from this device you will be able to address the problem with greater chances of a successful outcome.

FD CVM-A1500 factory

Analysing the installation using network analysers

As we have seen, it is crucial to have real information about the status of the electricity network in order to be able to detect whether a production stoppage is due to the quality of the power supply. For this purpose, there are network analysers which can help maintenance managers to understand what is going on at any given time in order to make the best decision, either to avoid production stoppages or to mitigate their impact.

To try to make performing this task as easy as possible, Circutor has designed its CVM-A1500A power quality analyser. It will quickly report any network quality incidents which may occur in a facility so that action can be taken straightaway.

This model is certified under the IEC 61000-4-30 standard and detects faults in power supply quality in the waveform from the half cycle (from 10 ms in 50 Hz networks and 8.3 ms in 60 Hz networks), providing complete information to maintenance managers about the problem. By installing several units at key points in the installation you can get a clear idea of when, where and how a power supply quality problem has impacted it.

The CVM-A1500’s user interface and integrated Web server provide easy, convenient and intuitive access to information about any power quality problems identified.

You don’t have to be an expert to interpret its data

The downside when it comes to analysing network quality has always been the interpretation of data by a specialist engineer. Some installations have quality equipment installed but it is not used because users have difficulty in interpreting its data.

Quality analysers are normally “black boxes” which do not provide information if they are not connected via data interpretation software.

So in addition to needing computer skills to download their data you also have to know about their computer program for interpreting these data. If you additionally combine equipment from several manufacturers, then the task is even trickier.

That’s why Circutor has developed a model featuring browsing by colour screens to provide relevant information for decision making.

ITIC curve

The CVM-A1500A analyser shows the ITIC (also CBEMA and SEMIF 47) curve on the screen. With just three clicks on the equipment, any maintenance manager can display the ITIC curve.

This curve shows red triangles each time an event occurs, quickly displaying how many quality events there have been and how damaging they have been for the installation. This means you can swiftly see what kind of problem you are faced with.

If the triangles are in the green zone, this means that there have been events (power surges or voltage drops) which have not harmed the electronic equipment in your facility. However, if the triangles are in the red zone, this will mean a swell which has most likely damaged your electronic equipment. The closer the triangles are to the top left, the more damaging they will be due to their high value and duration. By contrast, if the triangles are in the yellow zone this means that there have been voltage drops. These voltage drops may impact electronic systems leading to rebooting or stoppage due to low voltage.

Just by glancing at this screen, any maintenance manager will know why there might have been a malfunction. Furthermore, if it is repeated regularly, they will have more information to install a system which mitigates the event’s impact thus avoiding production stoppages and hence financial losses.

Installation events

In addition to the curves we have discussed above, the equipment has an event counter which shows you how many there have been in each phase so you will know whether the problem always comes from the same phase or if it is repeated regularly. To get a closer look, you can use the analyser’s screen to review each event individually and view it in detail. With several clicks on its screen you enter the event and see in which phase it took place, what its voltage percentage is, what voltage there was before the event (this helps you see whether it was a fast event due to switching or a slow one due to overloading), how long it lasted (from the half cycle) and on what date and at what time it occurred. Plus you can always enter the event to see its associated waveform, showing the voltage sinusoid to see exactly when it happened.

Other parameters to be checked to ensure the proper operation of an installation

We have seen how voltage events may bring about production stoppage which leads to financial loss. Furthermore, power supply quality analysers can help us avoid future problems in the installation by checking other relevant parameters.

Harmonics

Harmonic decompositionThese devices show harmonic decomposition up to 63, and you can see what level of harmonic load you have in the installation. Harmonics can impact the installation’s performance and also trip a circuit breaker or lead to overheating or malfunction of electronic loads.

Unbalances

Quite often installations have uneven currents in the various phases due to poor load distribution or a subsequent line extension. This effect may lead to current flowing through the neutral wire. In these cases it is essential to measure the current flowing through the neutral conductor to avoid possible insulation failures which can cause breakage that leads to swells, thus damaging components of the installation. Furthermore, if the installation has its own distribution transformer, this may overheat resulting in premature ageing and changing its useful life. To avoid these hazards, the CVM-A1500 network analyser measures neutral current along with any unbalance in voltages and currents and reports any situation that may entail a risk for the installation both onscreen and by email.

Data display on a PC

The CVM-A1500A analyser has a web server with built-in memory. Any user can access the logged data on a web browser (Internet Explorer, Firefox, Google Chrome, etc.) to monitor all parameters in real time, produce graphs and tables, view quality events and waveforms and extract data easily in Excel without having to be an expert in power supply quality software. Plus the equipment can be integrated with our PowerStudio Energy Management Software (EMS) and can be integrated into a complete network with equipment for usage management to provide an overview of the installation’s entire status.

Network quality at a glance

As we have seen, with the CVM-A1500A power supply quality analyser any user can have complete control of the parameters which may bring about a malfunction in any installation and also check where an electrical fault comes from, whether it be internal or external. By exporting data, maintenance managers can negotiate with the electric utility in case of a stoppage due to poor power supply quality or may even demand guarantees for all machines with anomalous operation as they can check whether the failure is the result of an external cause or due to malfunction of the machine itself.

Spain ranks fifth for electric vehicle charging points

Electric cars are an increasingly frequent sight in our cities. Spain is now the fifth most prolific country in Europe for zero-emission vehicles.

FD 5pais VE cargadorWhen sales of these vehicles began to take off, there were not so many charging points as there are now. Spain now has 3,856 public charging points for electric cars.

It is thanks to those charging points that Spain has the fifth largest infrastructure globally for these vehicles. The data were collected by Unieléctrica, based on figures from electromaps.com and the Spanish Institute of Statistics.

The United States occupies first place for infrastructure, followed by France in second, Germany in third and Holland in fourth.

New users of electric cars are recommended to find out all possible information from institutions and to ask in dealerships. Primary, they must be sure before buying whether they can charge their vehicle adequately in their location. The availability of charging points varies across the country. For example, in the region of Catalonia there are 939 charging points, and in Madrid there are 453.

Eco-friendly cars are becoming more popular across the globe. Numerous Governments across the world are supporting sustainable mobility. What once seemed impossible is now a reality; many companies are pursuing eco-friendly transport, and the number of private charging points is on the rise.

How do I charge my electric car?

All you need to do is connect your car to a charging point. You can usually find the cable in the boot of your electric vehicle. Once it is connected, the charging programme will begin automatically. The LED lights will indicate when charging begins and some cars have a charging current programme.

For the optimum charging of the battery of your electric car, you should be aware of the two different types of plugs. Around 30 models of zero-emission vehicles on the market have a type 2 “Mennekes” plug, which has been EU standard since 2013, designed by the alternative electrical charging company Mennekes.

For a quick charge, the Japanese electrical and automotive industry developed for 2019 the CHAdeMo connector. It is mostly used in Asia, but certain European electric car models are now using this kind of plug.

If you have an adaptor you can also charge your electric car battery at home, but only in an emergency, because domestic electricity infrastructure is not suitable for extended charging.

Recommendations for charging zero-emission vehicles

Tipo 2 ó Mennekes (IEC 62196-2)To fully charge your electric car battery, you need to ask two key questions: What kind of charging? What kind of plug?

Choose the charging mode (full or quick) according to your needs.

Energy Management Systems and consumption analysis

The growing importance of electricity costs in businesses or at home has sparked a keen interest in understanding this consumption.

If you want to save on energy costs, you have to discover the reality hidden behind every power socket. You can explore alternatives which will stop consumption figures from boosting the final amount to quantities beyond your budget.

Basics of electrical installations for energy optimisation

Before attempting to take any steps to reduce electricity costs, the internal electrical grid must be understood. There are three essential categories to be considered when analysing problems:

  1. The total power contracted. It is reflected in the electricity bill and follows a standard type of consumption that meets consumer needs.
  2. The pattern of consumption based on industrial or domestic usage. In practice, this means the installed devices and the energy each unit needs to consume to operate correctly.
  3. Energy consumption rate per device. This stems from the previous category. For example, it specifies the time used by each power consumption device. A fridge will usually consume a continuous amount, whereas a dishwasher will probably consume a different amount from month to month. If you are able to identify these variables, then it is easy to manage power consumption.

It is very useful and revealing to break down contracted power consumption per installed electrical appliance and usage times. If you are unable to find a decent alternative to your consumption, you can always compare rates and offers from electricity companies. All include a discount on electricity consumption subject to individual contract conditions that also need to be evaluated

Keys to understand and calculate electricity consumption

Your electricity consumption may be conveniently tracked by using measuring devices such as energy consumption analysers. Any deviation in the usual rate caused by a device's malfunction is immediately detected. It is as simple as comparing the amounts consumed by the same device for previous periods.

The analysis of over 250 electrical parameters with references to energy, cost and equivalence in emissions shows whether current regulations on Energy Efficiency are being complied with or not. The documentation provided allows you to quickly configure the system, enabling you to safely and reliably track the consumption of your private network. You no longer have to mentally calculate consumption since rates are conveniently updated and even different sources of power are recognised. This is the case, for example, with auxiliary power units or UPS (Uninterruptible Power Supply).

A definitive state-of-the art solution providing complete control over the operation of an electrical network. Corrective actions have been clearly indicated for any detected malfunctioning.

Spain, together with Germany, has the highest electricity rates in the European Union. The actions you take to save energy lower its effect on your budget by saving important costs in the medium and long term. The solutions to any doubts arising from this section may be found on commercial networks offering these products.

REC4. Comfort at home, continuity in infrastructures

Earth leakage protection is one of the most important systems in electrical installation safety.

Circuit breakers must always trip whenever a dangerous leakage level for humans is reached or they can cause economic losses to electrical installations. That said, these elements do not only trip on occasions caused by leakage in the installation, but due to external factors too, such as thunderstorms which frequently occur.

Self-reclosing RCCB devices are circuit-breakers with a built-in motor, whose function is to reclose if there is no permanent leakage in the installation.

This article presents a new design in Circutor's REC series, the REC4, as well as highlighting the benefits of installing such a device.

The device

FD REC4 3-en

The new REC4 is a development of its predecessor, REC3, in terms of size, while maintaining all its features. The device now takes up only a 3-module space, which means that it can be easily installed in new or existing electrical panels.

It is also the ideal solution for panels with limited space, replacing the standard earth leakage protection (2 modules) and the thermal magnetic circuit breaker (2 modules) with the REC4 (3 modules) and a unipolar thermal magnetic circuit breaker (1 module), also referred to as DPN. Automatic reclosing is therefore incorporated by taking up the same space, avoiding the need to enlarge the electrical panel.

REC4

The REC4 also includes the possibility to cancel the reclosing system by selecting manual or automatic mode, and may be sealed up to prevent tampering during maintenance work or once in operation.

Once installed, it has LED indicators to quickly, visually check its status (ON/triggered/reclosing) at all times.

To ensure full personal safety, the device is equipped with protective insulation, which deactivates the automatic reclosing system in the event of direct contact during handling, thus avoiding any injuries during start-up or maintenance work.

Its installation is really simple, since its compact size allows it to be fitted as a current circuit breaker, and the user does not need to make any type of connection between the circuit breaker and the motor, as it is completely built into its housing.

Maximum continuity, minimum space

FD REC4 espacio-en
 
The REC4 is a device designed for all those installations where service continuity is essential. As you will notice, there are many possible uses for Circutor's self-reclosing RCCB device, which is suitable for any type of electrical installation thanks to its compact dimensions.
Comfort at home

The REC4's functions make it particularly well-designed for domestic use, where most loads are single-phase. More and more devices operate autonomously and are controlled remotely. This is why RCCB tripping may cause several household problems.

FD REC4 vivienda1When we are away from home on holiday and the circuit breaker trips, the cables connecting electrical appliances such as fridges to the mains may become damaged, causing the contents of the fridge to get spoilt in a matter of hours. This problem causes economic losses in having to get rid of food and make us waste time cleaning it and switching it on again.

FD REC4 vivienda2Another example of the way the REC4 self-reclosing RCCB can be used is to prevent tripping from disconnecting the home's burglar alarm, leaving the premises unprotected against vandalism and theft. Installations such as air conditioning, lighting, garden irrigation or pool maintenance are also remotely controlled nowadays by mobile devices. The device will help us to keep them working at all times, avoiding surprises on arriving home or at our second residence, the latter being possibly the most important case for our self-reclosing RCCB device.

FD REC4 infra1

However, the advantages are not just restricted to guaranteeing constant functioning of household appliances when we are away from home. There will be numerous occasions on which we will appreciate the REC4 self-reclosing device, e.g. when the lights suddenly go out at home, sparing us the discomfort of moving in the dark to the mains panel to flip the switch.

Continuity in infrastructures

The main reason to equip infrastructures with the REC4 circuit breaker is to maximise single-phase load service continuity. The device will reclose almost instantly as long as there is no permanent leakage, avoiding shutdowns in different systems that lead to substantial economic losses which must be avoided at all costs.

FD REC4 infra2Wherever equipment is operating autonomously from a remote location, Circutor's self-reclosing RCCB will safely reclose in the event of protections tripping.

In the event of transient leakage tripping, the system will ensure that the installation continues to operate normally. On the other hand, if permanent leakage is really occurring, the system will try to reclose up to three times and if it the leakage persists, reclosing will not be completed, leaving the circuit open for a specialist to inspect it.

FD REC4 infra3For example, in the telecommunications industry it is very common to have different antennas spread over the country, with some of them located far away or inaccessible. A downtime in this type of infrastructure could lead to losses of around €30,000/min for the company, in addition to the cost and inconvenience of displacing personnel to the site to simply flip the switch.

Other examples along these lines would be public lighting installations, guaranteeing that the lighting system works in the city or on the roads, or the reclosing of low-cost petrol station facilities that do not have personnel on site to manually carry out reclosing. Instead of moving to locations to restore normal operation, the REC4 would restore the installation's proper functioning.

FD REC4 infra4As regards the services sector, having the self-reclosing RCCB would be an important asset in systems like lighting, air-conditioning, surveillance camera networks or uninterruptible power supplies (UPS) to keep them working at all times, both in small establishments and large stores or shopping centres.
