Product Description

Product Description

GYID series ground fault relay 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.
 

Feature

 

1. Monitor the insulation state of all internal Class Voltage(high voltage side)components of the 0~1000VDC DC floating system(IT system).
2. Measuring battery pack DC voltage
3. Continuous measurement of insulation resistance of 0~50MΩ
4. Communicate using the CAN bus interface
5. Monitor the positive and negative insulation resistance separately
6. Monitor the total insulation resistance and report the location of the battery insulation fault
7. Automatically adapt to existing system capacitor CY(CY≤4uF)
8. Operatingtemperature-40~+105
9. High internal resistance up to 10MQ
10. injected sianalamplitude±15V
11. Fault responsetime≤5s
12. High and low voltage side isolation voltage 3500VDC/2500 VAC(rms)
13. With CAN Bootloader, upgrade program by CAN
