Time synchronization
Switching to the test mode while the protection is in operation should only be undertaken
by especially trained personnel. Incorrect manipulations can cause false tripping, for
example, by inadvertently operating a tripping relay, simulating an incorrect disconnector
or circuit breaker status or activating a tripping input (for example, External TRIP).
