Overview
YSBJC DC system AC surge measurement and alarm device, real-time monitoring of the amount of AC entering the busbar in the DC system. When the AC value exceeds the set value, the equipment will alarm to avoid system instability caused by abnormal AC entering the DC system. It is mainly used in substations or power plants.
