Type D64L ground fault monitors are designed to monitor ungrounded supplies on three-phase AC power systems up to 600 V. If an insulation fault develops anywhere on the system between the source and the load, the D64L will detect it and give an alarm or trip, depending on the adjustable field settings selected. The D64L is ideally suited for systems supplied from the secondary of either an ungrounded delta or an ungrounded wye connected transformer. Because D64L has high immunity from the effects of voltage transients and cable capacitance, it may be applied in automotive, sub-sea, mobile lighting, portable generators, sensitive equipment and other installations where ungrounded systems are used extensively. The user is able to individually set the alarm level and the trip level from 20%-80% of the maximum leakage current limit of the D64L selected. Any leakage current above the alarm level will activate the alarm relay and light the alarm LED. Should the leakage current rise above the trip level, the trip relay and trip LED will activate.
