The ZJS-102 DC System Insulation Monitor employs the pure DC leakage current monitoring principle, featuring both balanced bridge and unbalanced bridge detection modes. It provides a real-time display of the leakage current for each circuit. The ZJS-102 online insulation monitoring system offers comprehensive DC insulation fault monitoring, capable of detecting various ground faults in the DC system. These include single-point grounding, multi-point grounding, two-pole grounding, AC intrusion, DC mutual interference, battery grounding and positioning, voltage balance, timing detection, pressure difference alarm, automatic calibration, and more. Additionally, it features instantaneous grounding monitoring and line selection alarm functions.
It comprises three essential components: the main controller (host), the current collector, and the dedicated DC leakage current sensor. The main controller serves as the central control unit for the entire system, functioning as the primary interface for monitoring information display and setting information input. Sensors are installed at each DC feeder outlet loop. Positioned between the host and the sensor, the current collector offers flexibility in installation location based on requirements. It can be directly linked to the host via the communication bus or indirectly connected through the cascade port of another slave machine, simplifying installation and wiring. Each current collector can connect with up to 8 sensors.More
