TEST-500D DC circuit breaker current injection test equipment adopts ARM Chip to control its output process and large capacity of toroidal transformers. It is equipped with LCD display; it can show DC primary current value, second voltage small signal measurement value, the action time of DC circuit breaker. Packing is used as aluminum alloy body with PC panel. TEST-500D is mainly applied to DC current sensor testing in the DC power system and contact resistance test which need large current. This model current injection test equipment is ideal for 1. performance and error tests of DC current sensors; 2. primary tests of DC protective relays; 3. large current tests on low-voltage and high-voltage DC circuit breakers; 4.commissioning tests that require variable DC currents.
