Product Details

The on-line insulation monitoring device of DC system balances the requirements of accuracy and safety of monitoring, and can detect all kinds of grounding fault, insulation decline, ring network state, AC series, DC interseries and other faults.The device combines the ping-pong principle and the passive monitoring principle in the active mode. Based on the multi-16-bit CPU parallel operation, the innovative distributed system architecture DADC and the advanced whole system analysis algorithm redefine the standard of the dc system grounding fault monitoring level.
