Functionality

The circuit breaker control function 52 is intended for circuit breaker control and status
information purposes. This function executes commands and evaluates block conditions
and different time supervision conditions. The function performs an execution command
only if all conditions indicate that a switch operation is allowed. If erroneous conditions
occur, the function indicates an appropriate cause value. The function is designed
according to the IEC 61850-7-4 standard with logical nodes CILO, CSWI and XCBR.
The circuit breaker, disconnector and earthing switch control functions have an operation
counter for closing and opening cycles. The counter value can be read and written
remotely from the place of operation or via LHMI.
