Air circuit braker test setup

This equipment is an Air Circuit Breaker (ACB) test setup,mainly used for testing,demonstration, and training purposes. It is designed to test the operation and protection functions of an Air Circuit Breaker under simulated conditions. The panel includes overcurrent and earth fault relays,ammeters,CT(Current Transformer)inputs,and control switches. By adjusting the current injection control,fault currents can be simulated to verify tripping characteristics,relay response,and breaker operation. The setup helps in checking trip timing,protection coordination,and breaker health without connecting it to alive power system
