Abstract: The system has at least one mainly horizontal first bus bar (51), a power switch (10) with two current connections (11,12), a first for connection to the first bus bar and two combination isolators (71-73) with isolation and earthing functions, whereby a housing of the first combination isolator (71) carries a section of the first bus bar. The housings of the combination isolators are oriented so that two drive devices (81-83) face in the same, predominantly horizontal direction.

Abstract: A method and an apparatus are disclosed for disconnection of a fault current which has occurred in an AC power supply system. A disconnection command which is produced in a protective device is supplied to a synchronization controller in order to open a circuit breaker, in which synchronization controller a command is delayed until the circuit breaker can be opened in synchronism with the power supply system. The method includes monitoring of the disconnection command emitted from the protective device and monitoring a fault-current signal, or a status signal emitted from the circuit breaker, and formation of an emergency disconnection command if the fault-current signal or the status signal is still present following a delay time after emission of the disconnection command, which delay time is greater than a sum of a natural response time of the circuit breaker and a time for quenching of a switching arc produced on opening of the circuit breaker.
