[Suitable for AC & DC Systems] GYID

Description

GYID series insulation monitor is used for real-time monitoring of insulation resistance to ground in 0~1000VDC floating DC systems and 0~750VAC floating AC systems; it can detect insulation faults such as equipment housing-to-ground and high-voltage-to-housing insulation failures.

• In DC systems, it can independently measure the insulation resistance of the positive and negative poles of the DC system to ground. In electric vehicle applications, it can reliably monitor insulation resistance under strong interference or complex driving conditions, such as acceleration/deceleration, braking, and energy recovery.

• In AC systems, it can suppress interference from high-frequency voltage harmonics and accurately measure the insulation resistance to ground of the entire AC system.

• DC System: Monitors the insulation status to ground of 0~1000VDC floating DC systems and accurately measures DC voltage.

• AC System: Monitors the overall insulation status to ground of 0~750VAC floating AC systems. Line selection is not available (it cannot distinguish which phase line has an insulation fault), and AC voltage measurement is not supported.

• Passive Equipment: Monitors the insulation status between equipment and housing or between equipment and ground.
