First trip measurement with TM1700 and TM1800
Test the breaker at first operation after a longer period of static position.Trip the circuit breaker from stationcontrol (Local or remote system). During operation coil currents are recorded by current clamps connected toTM1700 control part or TM1800 analog module. 3 phase timing are recorded by current clamps in secondarycircuit station of current transformers (in the bay). The “timing” current clamps are connected to the analogchannels.
