Overview
The YSBJC anti AC intrusion DC detection system is applied in substations or power plants to monitor the amount of AC entering the bus in the DC system in real time. When the AC value exceeds the set value, the equipment will sound an alarm To avoid system instability caused by AC entering the DC system due to abnormal reasons
