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 station

control (Local or remote system). During operation coil currents are recorded by current clamps connected to

TM1700 control part or TM1800 analog module. 3 phase timing are  recorded by current clamps in secondary

circuit station of current transformers (in the bay). The “timing” current clamps are connected to the analog

channels.
