The three pillars of energy transition

Energy transition is a necessity rather than an obligation; to meet climate targets we must move towards a sustainable energy model that promotes the use of renewable energy sources.

Industrialised countries generate most of their electricity from conventional power plants, such as coal, gas or nuclear. These plants provide a huge economic benefit for the generating companies, where users pay for their energy needs by buying electricity and fuel from the relevant public utility companies. This form of supply is easy to use but often entails high costs and is quite inefficient in terms of the rational use of energy.

Energy transition is difficult but not impossible; the first step is to change the way energy is generated. For this, the generation points have to be decentralised. This energy model is known as Distributed Generation (DG). This system is based on generating energy at the same point where it is consumed, directly reducing network losses, which contributes to environmental preservation through the use of renewable energy sources.

Distributed Generation has multiple advantages compared to the conventional system, offering technical, economic and environmental benefits.


It improves the quality of the electric service because it reduces the probability of failure due to downed high-voltage power lines, as the percentage of use of those lines is reduced.

DG systems are modular and give the electric power distribution system flexibility. This means simple installation in a short time. It also provides the operating system with a great advantage, maintaining the flexibility of its total capacity, increasing or decreasing the number of modules.

DG reduces energy losses in the distribution and transmission lines. 


It avoids investment costs in transmission and distribution, generating a lower cost in electrical infrastructures and thus achieving operation and maintenance savings.

It reduces fuel costs due to improved efficiency in the case of cogeneration applications. These systems use waste heat for reuse in heating, cooling or to increase their efficiency by generating electricity, saving primary energy.


It reduces the emission of pollutants. DG favours self-consumption using in situ generation systems. This helps to reduce the consumption of primary energy from conventional sources by generating cleaner energy, like that from a photovoltaic system, and avoids emissions generated due to transmission losses from power plants to cities.

These systems can include multiple generation and storage systems, allowing generation by conventional systems to be shifted to solar or wind generation.

However, to achieve energy transition, it is not enough to decentralise the generation points and make use of clean energy sources, the way energy is consumed also needs to be changed. Therefore, success lies in changing consumer awareness and making rational use of energy resources.


Reducing energy consumption is based on the following three key pillars:

Electrical Energy Efficiency

This is the reduction in the power and energy required from the electricity system without it affecting normal activities carried out in buildings, industries or any transformation process. An electrically efficient installation enables its technical and economic optimisation, or rather a reduction in its technical and economic operating costs.

In short, energy efficiency involves:

  • Helping the sustainability of the system and environment by reducing CO2 emissions through optimisation of the energy demand.
  • Improving the technical management of facilities by increasing their efficiency and avoiding production downtimes and possible failures.
  • Reduction in both the economic cost of energy and the operation of facilities.

Electrical Energy Efficiency

Electric mobility

Energy transition is not possible without electric mobility; the electric vehicle is the future. Transition to the electric vehicle means a drastic reduction in greenhouse gas emissions. You only have to think about the difference in efficiency of a combustion engine and an electric motor.

An electric motor has an efficiency of around 95%, whereas a heat engine has an efficiency of around 30%. To travel 100 km, an electric car consumes three times less energy than a conventional vehicle.

This is based on the premise that the energy used by electric vehicles can come from clean sources, whereas the energy used by a conventional vehicle can only come from fossil fuels.

Electric mobility

Nearly zero-energy buildings (nZEB)

Consumption in buildings constitutes 40% of Europe's total energy. Reducing consumption in buildings is one of the main points of action to reduce energy dependence and thus comply with international agreements to slow down climate change.

This was the reason behind European Directive 2010/31/EU, on the energy efficiency of buildings, under which all member states must take steps so that as of 2020, all new buildings have nearly zero-energy consumption (2018 for public buildings).

Nearly zero-energy buildings nZEB have a very high level of energy efficiency and comfort, and very low energy consumption, coming mostly from renewable sources in situ or the environment.

Nearly zero-energy buildings (nZEB)

In short, energy transition involves a series of complex challenges to be addressed but, if managed properly, the benefits of the new energy model will help to halt climate change and improve everyone's quality of life.

The CDP Dynamic Power Controller, now compatible with HUAWEI inverters

The CDP dynamic power controllers for CIRCUTOR photovoltaic inverters (CDP-0, CDP-G and CDP-DUO) are now compatible with the SUN2000 range of inverters made by HUAWEI, a leading global company in the research and development of electronic and communications equipment.

The SUN2000 KTL range by HUAWEI consists of grid-connected inverters with a built-in controller to improve the efficiency and performance of the inverter. The SUN2000 KTL product range has power ranging from 8 kW to 42 kW. These inverters do not require transformers (TL) and they also have a built-in DC disconnect system for safe and simple maintenance.

The HUAWEI inverter models compatible with CDP controllers are as follows:


  • HUAWEI SUN2000-12KTL
  • HUAWEI SUN2000-17KTL
  • HUAWEI SUN2000-20KTL
  • HUAWEI SUN2000-23KTL
  • HUAWEI SUN2000-28KTL
  • HUAWEI SUN2000-33KTL-A
  • HUAWEI SUN2000-36KTL
  • HUAWEI SUN2000-42KTL
Obtain legal authorisation for your photovoltaic energy system

CDP devices allow you to control the power generated by photovoltaic inverters according to the installation's consumption value (or another selectable value) to prevent surplus power from being injected into the grid or into generator sets. This allows you to obtain legal authorisation for self-consumption installations in places where it is necessary to ensure 0 injection into the grid.

The aim of the CDP range is to reduce the energy obtained from the grid, always prioritising the clean energy generated by photovoltaic panels.

The communication between the CDP and the inverter is via RS-485 bus, which allows up to 100 inverters to be connected, although in the vast majority of domestic installations, the number of inverters ranges from 1 to 3.

With this new integration, the CDP devices have improved compatibility by adding one of the most popular brands on the market to its system, thus ensuring the accurate and simple management of photovoltaic production control.

So CIRCUTOR is offering the market a fully autonomous system that enables the smart management of energy in the installation.

RECmaxCVM a versatile unit that will analyse and protect your facility

The new REC max CVM, reclosing circuit breaker and earth leakage protection, now with measurement included.

Current situation

Currently, the vast majority of production processes in industry and services for people require a continuous supply of electrical energy.

Ensuring electrical service continuity is vitally important to maintain a business model; production line downtime or the disconnection of a refrigerating chamber will mean significant financial losses for a company.

Electrical service continuity ensures highly efficient energy management (ISO 50001) for businesses and improves the quality of life of people in their homes and leisure facilities.

Obviously, the safety of people and equipment comes first, but most of the time avoidable and unwanted tripping of the protection elements occur in situations where no electrical hazard is involved.

There are numerous causes of these trips, so analysing the installation helps us to identify what triggered them, to enable us to deal with them as quickly as possible.

In light of these issues, it is necessary to install smart earth leakage and circuit breaker protection devices with automatic reclosing, which ensures as little service interruption as possible. If this device is also capable of performing measurements, you get a unique solution that covers the three most important aspects for maintaining the safety, measure and continuity of your electrical installation. 3 systems in 1: protection, analysis and reclosing.

Safety, quality and continuity. Protection, analysis and reclosing


The new RECmaxCVM is a system that combines circuit breaker and earth leakage protection. It has an automatic reclosing system, as well as a power analyser, included to measure the electrical parameters of the circuit it is protecting. A system designed for critical environments and sectors where electrical service continuity is vitally important.

Versatile System.

  • Available in 2- and 4-pole for all types of installations.
  • Adjustable trip sensitivity: 0.03-0.1-0.3-0.5-1 A
  • Adjustable trip time: Instantaneous - Selective: 0.1 - 0.2 - 0.3 - 0.4 - 0.5 - 0.6 - 0.8 - 1 s

Reduces unwanted tripping, maximum service continuity.

  • Type A super-immunised protection.
  • Automatic reclosing system.

Measurement of all of the installation's electrical parameters.

  • Built-in CVM series power analyser.
  • It has RS-485 communication (Modbus RTU).

Installation control.

  • 2 inputs for remote control of the device.
  • 2 outputs to signal the status of the installation.

The RECmax CVM kit comes with all accessories included, both the MC measuring transformer and the WGC earth leakage transformer.

  • Over 250 electrical variables.
  • DIN Rail format.
  • Trip curves: C/D
  • Leakage current measurement with the external WGC earth leakage transformer.
  • Current measurement with the MC series efficient transformers (.../250 mA).
  • Compatible with PowerStudio / PowerStudio Scada / PowerStudio Scada Deluxe software
Designed for saving

RECmax CVM is designed for saving. The combination of a CVM power analyser and an automatic reclosing protection device make it a compact and affordable system. A single system that offers protection, electrical service continuity and grid analysis.

1. Saves time and space
Space is normally limited on electric panels due to excess equipment and wiring. Therefore, RECmax CVM with its small enclosure, can be suitable for any electric panel and free up space on the DIN rail.
RECmax CVM avoids excessive wiring thanks to its Plug&Play system, as it is not necessary to wire the power supply for the reclosing motor or the analyser module, as it has a system that is self-powered directly from the power line.
Saves time and space
2. Reduces unwanted tripping
has ultra-immunised circuit breaker and earth leakage protection. Many earth leakage relays on the market do not have ultra-immunised protection. What sets the RECmax CVM apart from normal earth leakage relays is that it has a high frequency filter that enables it to determine whether there is really a leakage problem in the installation. In other words, it determines whether there is a real leakage and the effects of the harmonics on the grid.
This means that unnecessary tripping due to harmonics is avoided, thus ensuring service continuity.
The main advantages of ultra-immunised protection over conventional protection are:
  • Greater accuracy in trip sensitivity, between 85%-100%. Conventional earth leakage relays can trip at 50% of their sensitivity, unwanted tripping caused by leakages that do not generate any hazards.
  • Frequency response with filtering of leakages at high frequencies; it distinguishes between real leakages and harmonic distortion
  • Higher immunity against network transients of up to 3 kA for 8/20 µs impulses, thus avoiding false tripping caused by network transients.
3. Reduces production and/or service losses
Unwanted tripping of protection elements is normally resolved with simple manual reclosing. The problem arises when we require continuity in our process but we do not have the means to perform such reclosing. In many factories and buildings there is no 24-hour maintenance service. When faced with this problem, the best solution to ensure electrical continuity is to have an element with a smart automatic reclosing system.

RECmax CVM has a motorised system that reconnects the protection element in the event of unwanted tripping. RECmax CVM is a smart system, reclosing after 3, 20 and 180 seconds respectively; if it detects that the problem is persisting, the unit is permanently disconnected to keep the installation safe.

4. Saves energy
Knowing about our use of energy resources is the first step towards energy efficiency. If we do not know about our consumption patterns, there is no way we can act in the key areas where savings can be made in our installation.
In light of this, including a power analyser in a single protection element will inform us of our energy use, so that we can try to optimise it in our production process.

At the same time as protecting people and the installation, we control and reduce unnecessary and inefficient consumption within it. The CVM analyser measures over 250 electrical variables. Thanks to the display or RS485 communication, we know how, when and where our energy costs are arising.

A complete solution. Protects, Measures and Reconnects

RECmax CVM is a complete solution that is perfect for facilities where it is vitally important to maintain the electrical service, such as production lines, data centres, supermarkets, etc. But always while protecting the safety of people and equipment.

RECmax CVM has 2 inputs, one for the device's remote control. The system allows you to remotely reclose the circuit breaker, thus avoiding the need for manual reclosing.

With the second input, RECmax CVM allows you to disable automatic reclosing, making it suitable for facilities that only require protection and measurement.

Furthermore, RECmax CVM has 2 outputs that allow us to know the protection status; the system generates alarms to report a change in the circuit breaker, thus informing us of the conditions in our facility in real time.

It also generates locking alarms, so that we know if we have locked the automatic reclosing system.

Plug&Play System Simply connect the phases and the system will be integrated into the electric panel.
