This function provides:
Each Sepam is capable of:
- perfect tripping discrimination with phase-to-phase and phase-to-earth short-circuits, on all types of network
- faster tripping of the breakers closest to the source (solving the drawback of conventional time discrimination).
Each Sepam is capable of:
- sending a blocking input when a fault is detected by the phase overcurrent and earth fault protection functions, which may or may not be directional (ANSI 50/51,
- and receiving blocking inputs which inhibit protection tripping. A saving mechanism ensures continued operation of the protection in the event of a blocking link failure.
