isolated neutral system SGR ground fault protection is a combination of GPT & ZCT. This method, the ground-fault accident, the number of ampere degree less current flows on the grid Impact and the critical load without ground-fault accidents Trip not able to operate. But if it does not fit the wiring and polarity behavior because a malfunction or Through a mock exam in advance to prevent malfunction Equipment as equipment for testing the virtual non-grounded system of ground-fault accident scene Can be used for three-phase AC power supply (0 ~ 600V).
