Blue Jay GYID series Electric Vehicle DC Insulation Monitoring device is used for real-time monitoring of the insulation resistance between the high voltage components (0~1000Vdc) and the chassis (earth) of the power battery pack (pure electric or hybrid) power supply system. The measurement technology used in this product can monitor the insulation faults on the DC side, the AC side, and the motor side; The ground fault detection DC system can simultaneously monitor the positive and negative asymmetric insulation faults and symmetrical insulation faults; it can monitor the internal insulation faults of the battery pack and locate the fault point; It can monitor in the case of short circuit on the high-voltage DC side; in the case of high-intensity interference, such as acceleration, deceleration, and energy recovery, it can also reliably monitor insulation resistance.
