Compensating Reactor Description

 

High Voltage testing is done to check the integrity of Electrical insulation. Electrical insulation acts as a capacitive load. Also additional capacitance in the test system like Measuring Capacitor, Test Transformer inherent capacitance, Coupling capacitance and any stray capacitances contributes to the total capacitance load on Test Transformer. In net effect, the load on the Test Transformer is Capacitive in nature. Since load is of the capacitive in nature during HV Insulation testing, Reactive power will come into picture.

The air insulated compensating reactor is connected between the regulating transformer and the test transformer. Following are the benefits of Compensating reactor.

Benefits of Compensating Reactor

  • Loading of the power source comes down
  • kVA of the regulating transformer reduces
  • Input power cables rating comes down
  • Primary & Coupler winding loading comes down
