ZJS-102 DC System Insulation Monitor

ZJS-102 DC System Insulation Monitor

ZJS-102 DC System Insulation Monitor is a highly accurate and secure online monitoring equipment for DC system insulation. It is designed for the measurement of different types of ground faults, insulation decreasing, AC signal interruption, DC signal interruption, and so on.

This insulation monitoring device detects DC leakage current, mixed with balanced & unbalanced bridge detection mode, and can display the leakage current of each sub-export loop. The ZJS-102 DC System Insulation Monitor integrates voltage transient capture and current synchronous detection and records voltage, and current fault curves to achieve instantaneous grounding monitoring and line selection alarm functions.
