It is a low voltage system protection to selectively separate fault points from the system to minimize the influence of fault. In this protection type, only the circuit breaker installed at a fault point is operated while the other feeder can be used continuously. In this protection type, upstream circuit breakers can be tripped earlier than downstream circuit breaker for back up protection. So, it is applied to the smaller breaking capacity than the calculated value at the downstream circuit.
