process of the protected object must have been tested as individuals and set in operation.
The breaker must be ready for an open-close-open cycle.
Scheme performance test is the final test that should be carried out before the protected
object is taken into service.
Due to the complexity in combination with already performed tests, it is not necessary
to test all protection functions and all fault types in this process. The most important
protection functions in the terminal for single line to earth fault and phase-phase fault
