DC insulation monitoring device ZJS-102

RS485for marine applicationfor PV applications

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. ·Monitoring various faults in the DC system:all types of grounding, abnormal voltage,voltage difference. ·Monitoring AC cross-current faults in DCsystems. ·Monitoring DC system mutual channeling(ring network) faults. ·It can accurately detect the distributedcapacitance of the DC system to the ground. ·Detect the leakage current of all branches. ·With battery pack grounding monitoring andpositioning functions. ·Multi-caliber open and closed CT can meetall usage scenarios.
