How to avoid penalties on electricity bills (industry and services)

If you run a business, one of the things you will be concerned with is your electricity bill. You will no doubt have heard of reactive energy and how it can affect the cost of your final bill. But what exactly is this type of energy?

What is reactive energy?

So-called reactive energy is the electrical energy that certain electrical appliances and units take from and return to the grid without using it. This means it is not actual consumption, although there is a cost to utility companies as they have to generate and transport it, which is why this energy can be found on your bill, especially when it accounts for a high percentage of consumption.

This type of energy is mostly required by units that generate a magnetic field in order to work. While private properties may have practically no reactive energy consumption, for businesses it can be a significant expense and occasionally a source of problems.

There are steps you can take to lower the penalties imposed for the reactive energy required by the units you have installed, thus correcting the so-called power factor. This factor measures the ratio between active power (actual operating power) and the total power consumed or the apparent power. Its value will be 1 or less, representing the actual efficiency of the electricity consumption. The ideal power factor value is therefore 1, which would imply a better use of energy.

How to cut your electricity bill by reducing reactive energy

There are different measures that can be implemented to bring the power factor value as close as possible to 1. One of the options you will have to consider, if you haven't already, is installing a capacitor bank, consisting mainly of a regulator, contactors and capacitors.

The presence of harmonics in the facility must also be assessed, installing a harmonic filter whenever necessary. These elements are generated as a result of a distortion of the electrical current caused by certain electronic units. The problem is that the resonance they can generate ends up causing damage, such as overheating or system degradation.

In any case, a thorough study of the electrical facility would have to be carried out and any possible damage, especially to the capacitors, repaired. You should therefore consult an expert who can advise you on the best options for your facility.

In short, reactive energy can be a major expense in a company's electricity bill, making it vital to reduce this type of consumption in order to save unnecessary costs. Please contact us if you would like an expert to review and study your facility with a view to cutting your electricity bills. Our experts will be happy to answer any questions you may have.

Check each parameter of your electrical installation

New needs in the sector

The new CVM-E3-MINI analyser is specially designed to carry out the best electrical and energy variable management in any type of installation, adapting to new international standards for measuring and managing energy efficiency.

In line with the latest international standards, such as European Directive 27/2012/EU or National Electric Code 56/2016 (in Spain), the unit provides the user with the level of CO2 emissions of the installation, line or machine, as well as the monetary cost of the energy consumed or generated in each situation.

Check each parameter of your electrical installation
Everything that you need to know about your installation
  • Measures and calculates any parameter in your electrical network
    The CVM-E3-MINI provides real-time measurements of more than 250 electrical parameters, including energies, cost and emissions, both in terms of consumption and generation. The unit measures the maximum and minimum RMS values of any instantaneous variable, as well as the harmonic breakdown up to the 31st harmonic.
  • Separates the consumption of two sources of energy
    The unit features a digital input for changing the tariff. In this way, the unit is able to save the incremental values of two sources of energy, either from the electrical network or the auxiliary energy generation system (fuel generator or UPS).
Manages your installation

It measures the operating times in order to carry out the necessary preventive maintenance of the elements of the line or machine in which it is installed. In this way, the person in charge of maintenance is able to replace all elements that could cause faults before they occur, preventing production line downtimes and the indirect costs associated with this.

The device features a transistor output for interacting with the system once an alarm associated with an instantaneous parameter appears, fully programmable by the person in charge of maintenance.

Prevents configuration errors
The unit can be configured via the free software PowerStudio. This software also allows any wiring issues on the device to be resolved remotely, without having to wait to stop production, thus avoiding erroneous data in the readings.
  • It resolves current transformer installation errors
    If a current transformer has been installed incorrectly, the unit will provide incorrect measurements. Using the software, it is possible to rotate a transformer without having to physically modify the wiring, thus avoiding reading errors and any electrical risk, as it is not necessary to interact with the power system.
  • It resolves voltage and current correspondence errors
    If the voltage connections are not on the same line as the current transformers, the unit will show erroneous values in the cosφ and power factor measurement, resulting in an erroneous power and energy reading. Via the software, it is possible to change the position of the voltage phases so that they correspond to the current phases without having to physically modify the wiring, thus avoiding reading errors and any electrical risk, as it is not necessary to interact with the power system.
Increased safety
The new CVM-E3-MINI features a new Plug&ON system with plug-in terminals to facilitate the installation of the device. These terminals are totally protected by sealable terminal strip covers to avoid any tampering or accidental disconnection due to the voltage of the wiring itself.

Increased safety

More versatility
The unit features an integrated Modbus RTU and BACnet protocol, providing versatility in terms of its installation in different types of installations, both in buildings and in industry settings. For those installations in which it is necessary to install the unit in panel format, the CVM-E3-MINI features a 72x72 mm adaptor for any assembly requirements.

More versatility

The best visibility
It ensures the correct display of data for distances of up to 3 m, avoiding having to open the panel to check any electrical parameter.

 

The best visibility


"Without a doubt, the new image of the CVM-E3-MINI power analyser from CIRCUTOR
is in keeping with current times and its features also respond to the needs of the sector."

Smart charging points: the best option for your residential complex

Electric vehicles are becoming more and more widespread, leading to the need for smart charging points to ensure operation. These charging points can be installed in a wide range of places, including the residential complex in which you live.

Where to charge an electric car

The electric vehicle has arrived, and is destined to play a major role in vehicle fleets in the not too distant future. Adaptation to this new type of vehicle must therefore start now. Just as with fuel-powered cars, electric cars need to be topped up. Charging points –which are becoming increasingly commonplace in cities– are therefore essential.

These points from which to charge your electric car can be located indoors or outdoors and can be either private top-up points or part of a public network. In this regard, an excellent option for your residential complex would be to install a smart charging point where sustainable vehicles can top up their batteries. You will be able to charge your vehicle every day without any problems.

What are smart charging systems?

What exactly are these systems? These charging points allow vehicles to be topped up efficiently. The system combines an electric charging unit with a series of parameters to ensure the vehicle’s battery is topped up at certain times of the day. It is a smart system, which charges batteries based on the cost of electricity throughout the day or at times of lower electric consumption in the building.

Furthermore, this smart charging system keeps track of which users top up their vehicles at the charging point and how quickly each electric vehicle must be charged. These points are ideal for charging your electric car.

Benefits of installing a charging point in your residential complex

You may ask what use a charging point is in your residential complex if there is already a public network. Public networks are not yet very widespread, meaning a top-up point such as this ensures your vehicle can be charged every night. In fact, by morning it will be fully charged and ready to use.

Moreover, the smart system is equipped with user identification to prevent unauthorised use. It should also be remembered that having a charging point in your residential complex will avoid the need to queue up and wait at public top-up points.

As you can see, electric vehicles are the future and require a place to recharge. Smart charging points are therefore an excellent idea in all residential complexes. Do not hesitate to contact us if you would like more information or advice.

Do you know how to compensate instantaneously without worrying about harmonics?

For all those installations where it is necessary to compensate instantaneously reactive energy, both inductive and capacitive without the need to install power capacitors, the solution is SVG series (Static Var Generator).

There are very particular cases where conventional capacitor banks cannot compensate the totality of the installation's reactive power or are not able to work properly due to network characteristics. The new SVG devices are capable of compensating instantaneously reactive energy in order to make an accurate adjustment of the cosϕ, avoiding penalties in the electric bill for both excess reactive inductive and capacitive energy (depending on the tariff system of each country).

The principle of operation of a Static Var Generator is to inject current in the opposite direction to that consumed by the installation, adjusting the cosϕ instantaneously, with a response time of 20 ms. In this way the device avoids the installation of power capacitors and all possible resonance effects in the network (increase of THD% level) that can damage the components of the installation.

This makes SVG ideal for its installation in situations where conventional equipment cannot compensate or work properly:

  • Installations with fluctuating loads
  • Installations with capacitive loads
  • Installations with unbalanced consumption (difference in consumption on each phase)
  • Installations with high harmonic distortion levels (THD%)
  • Lines with constant voltage fluctuations
