GYID Electric Vehicle DC insulation monitoring device,to monitor the positive and negative
Inquire NowThe GYID Electric Vehicle DC Insulation Monitoring Device is an essential tool designed for real-time monitoring of insulation resistance in both DC and AC floating systems. With the capability to measure insulation resistance of 0~1000V DC systems and 0~750V AC systems, this device ensures safety by monitoring insulation faults between the equipment’s shell and ground, as well as between high voltage components and the shell. It is particularly effective in electric vehicle applications, maintaining reliable performance even under challenging conditions such as acceleration, braking, and energy recovery. The GYID device also effectively filters high-frequency voltage harmonics in AC systems, providing accurate measurements of insulation resistance.
Features
– DC System: Monitors ground insulation of 0~1000V DC floating system.
– AC System: Monitors ground insulation of 0~750V AC floating system.
– Passive Equipment: Monitors insulation status between equipment and housing or ground.
