Next, different cases will be described.
•
The feeder and supply will trip their functions as they see the fault. Supply’s t
ime of
operation is shorter than feeder’s time, so the feeder will open its breaker, making the fault
disappear, and it will block the supply trip output preventing the opening of the supply’s
breaker.
•
The feeder and supply will trip their functions as t
hey see the fault. Supply’s time of
operation is larger than feeder’s time, so the feeder will open its breaker, making the fault
disappear, and block the supply function. The supply will not trip because the feeder makes
the fault disappear before its time of operation is finished.
•
The feeder and supply will trip their functions as they see the fault. Supply’s time of
operation is shorter than feeder’s time, so the supply function will trip but it will be blocked
by the feeder. When the feeder trips, it is not able to open its breaker so the supply will trip
once the block disappears since it can still see the fault.
