12 Levels Three-Phase Reactive Power Control Relay

The reactive power control relays are designed to decrease the reactive powers (inductive and capacities) not used by the loads in the system and drawn from the network due to the characteristics of the loads

It intervenes by activating a capacitor with suitable values if inductive power is drawn from the network. It intervenes by activating a shunt reactor with suitable values if capacitive power is drawn from the network.
You are requested to enter the current transformer value at first when it is energized after the connections of the device are completed. After you enter and approve this value, the system controls the transformer terminals according to the power it draws. After this test is completed, it starts the stage test and tests all stages. After the stage test is completed, it starts to intervene according to the system requirement. It has the characteristics indicated below.
3-phase voltage and 3-phase current transformer
It can compensate the inductive and capacitive systems.
Single phase, two-phase and three-phase capacitor and shunt reactor may be connected.
It shows the active power, reactive power, Cosφ, THD, total active and total reactive energy values of each phase on LCD display.
It shows the 3-phase current, 3-phase voltage or 3-phase Cosφ values on the display.
It saves the total active and total reactive energy values.
The stage (capacitor and shunt reactor) value can be entered manually.
It shows the capacitor or reactor stage values individually for each phase.
The system intervention time can be adjusted.
Capacitor discharging time can be adjusted. Inductive/ Active and Capacitive / Active ratios (%) can be adjusted.
It saves the reactive power flow of the system.
Menu is password-protected.
It saves the number of stage use.
It provides equal number of stage use for the stages with the same values.
It shows the inductive/active and capacitive/active ratios reached.
It can set the inductive/active and capacitive/active ratios desired to be reached.
The stage layout time between two stages can be adjusted.
Off set stage can be created.
Time of intervention in the capacitive loads can be changed.
Time of intervention in the inductive loads can be changed.
