JY1000 Insulation Monitoring Relay

JY1000 Insulation Monitoring Device are insulation monitoring devices that integrate various high-voltage monitoring functions, including DC-to-ground insulation resistance monitoring (real-time monitoring of positive and Pile special function), voltage reverse connection alarm, DC capacitor discharge (special function for DC charging pile) and other safety monitoring functions. It can be used in various DC systems such as electric vehicle DC charging systems, photovoltaic systems, energy storage systems, and DC grids.

This ground fault detection relay has the insulation monitoring start-stop function. After the insulation monitoring is started, it can monitor the
insulation resistance of the positive and negative electrodes to the ground in real time. The monitoring results are not affected by DC voltage fluctuations, and are not affected by the symmetry of the positive and negative insulation resistance.
