According to the electrodynamic principle, the magnetic field that provides the magnetic field required for consumers such as transformers and AC motors is called reactive current. The unit of the reactive power is KVAR. Reactive power causes a phase difference between current and voltage. Compensation systems are installed in enterprises, workplaces and factories in order to eliminate the difference difference. Reactive power control relays used in compensation systems are the most important element of compensation that activates capacitors and/or shunt reactors according to need to balance the active power and reactive power rates in line with the need for plant. Reactive power control relays measures and presents various current, voltage, energy, power, harmonic parameters of the network as well as active and reactive power.

Sigma analyzes reagent power control relay, system and system requirements. As a result, if there is an error in the system such as the wrong connection error in the system, it changes the connections within itself, and in cases where the relay is lacking the number or power of the reactor reactor levels or power, the user advises the user for the capacitor and/or shunt reactor values ​​to be added in the compensation.
