ZJS-102 Insulation monitoring system is a highaccurate and secure online monitoringequipment for DC system insulation. It isdesigned for the measurement of differenttypes of ground fault, insulation decreasing,AC signal interruption, DC signal interruptionand so on. Monitor detect DC leakage current, mixed withbalanced & unbalanced bridge detectionmode, can display leakage current of each subexport loops. It integrates voltage transientcapture and current synchronous detection,records voltage and current fault curves toachieve instantaneous grounding monitoringand line selection alarm functions.
