4.12. Trip block for switch disconnector
Some transformation centers use a combination of switchgear and fuses for cutting out.
Switchgears have a limited opening current. As a result, the fuses are responsible for cutting out
the circuit for high current short circuits, as the switchgear would be destroyed if opened in this
situation. In order to deal with these situations, tripping is blocked when the phase current
exceeds a pre-set value.
