GYID series insulation monitor is used to monitor the insulation resistance between high voltage components (0-1000 Vdc. /0-750Vac.) and automobile chassis (earth) of power battery pack (pure electric or hybrid) power supply system in real time.
The measuring technology used in this product can monitor the insulation faults of DC side, AC side and motor side; can simultaneously monitor the asymmetric insulation faults of positive and negative poles and symmetrical insulation faults; can monitor the internal insulation faults of battery packs and locate the fault points; can monitor under the condition of short circuit of high voltage DC side; in the case of high intensity interference, such as acceleration, deceleration, energy recovery, the insulation resistance can be reliably monitored. fault information (insulation fault, overvoltage, self-error, etc.) is output through CAN bus interface.
