Ungrounded: There is no intentional ground applied to the system-however it's grounded through natural capacitance. This decreases the current at the fault and limits voltage across the arc at the fault to decrease. Five-, ten-, and fifteen-minute outage pickup faster operation at high currents to as much as 70-cycles faster at lower currents.

Therefore, the correct wiring is: the tester IA is connected to the B phase of the high voltage side, the tester IB is connected to the B phase of the low voltage side, the tester IC is connected to the a phase of the low voltage side, and the neutral line of. There is a grounding jack next to the power jack to facilitate the tester to ground the. Over voltage relays are electrical protection devices that are used to prevent system voltage from exceeding a predetermined value and duration. What is an Over Voltage Relay? What is an Undervoltage Relay? When the voltage and time values cross, a tripping signal is sent to circuit breaker. A relay protection tester is a core device used to verify the performance of relay protection devices. Its working principle can be summarized as "signal excitation – behavior detection.
