Reactive power capacitors

The so-called reactive power often contributes to the inflated electricity bills. This is energy that, despite being consumed, is not converted into useful work or heat. In order to reduce the costs of electricity consumption and at the same time increase the stability of the power grid, it is necessary to select an appropriate method of compensating inductive or capacitive reactive power. Specialized devices - reactive power capacitors, which are available in our offer, are used for this purpose.

What is reactive power?

Reactive power (inductive and capacitive) is electrical energy that oscillates between elements of an AC circuit. Unlike active power, it is not converted into useful work or heat. Most receivers use both active and reactive power, so it is needed. However, reactive power causes an increase in current intensity, which in turn causes electrical energy losses in devices. For this reason, excess reactive power is subject to compensation. For this purpose, reactive power capacitors are used.

Reactive power compensation devices Nn

There are a number of solutions for reactive power compensation, including: • static reactive power generators, • automatic capacitor banks, • low-voltage capacitors, • filter and compensation chokes. The method of reactive power compensation should be adapted to the needs of a given installation, which requires precise measurements of the power quality and power profile using specialist measuring instruments. Low-power capacitors differ in many parameters, purpose and degree of resistance to interference. Attention should be paid to the capacity, dimensions, rated voltage and presence of plug-in terminals.

Why is it worth using reactive power capacitors?

Sources of reactive energy include lighting fixtures (including poor quality LEDs!), fans, electric motors and many other devices. The cost of introducing reactive energy into the network appears on the bill after exceeding the limit (reactive power factor) agreed with the energy supplier or for each introduced var in the case of capacitive power. It is worth knowing that exceeding the established limit is not a major challenge - also for smaller companies and institutions. Compensation of reactive power through a properly selected capacitor allows you to optimize your electricity costs, improve the efficiency of cable lines and transformers and increase the durability of the network.
