Sanion’s 154kV busbar protection panel, which is developed and manufactured by pure domestic technology, consists of multiple bay units (BU) which monitor the current of each feeders connected to the busbar and collect status information of circuit breakers and disconnecting switches. It also consists of a central unit (CU) which performs current differential protection by using the current values and status information received from the bus. In addition, CU measures the voltage of each busbar to use it for fault detection.
