AEMC AN-1 Meter and Probe for Leakage Current Testing

The AEMC AN-1 Meter and Probe for Leakage Current Testing generates a temporary grounded artificial neutral to permit the measurement of fault currents on ungrounded three-phase systems. Performs a cyclic grounding technique which limits the possibility of insulation faults within the instrument, limits instrument overheating, and permits accuracy of actual fault currents. The relay closure time is adjustable to Fast (0.5 seconds) or Slow (2.3 seconds). An audible buzzer sounds whenever a neutral connection is grounded. Three LEDS (one for each phase) shows the status of each phase before the measurement, in addition to a green LED to confirm the instrument is ON.
