Testing the trip delay (PF Trigger: Example = 0.86 lagging):
•
Feed the rated voltage and rated current in phase to the measuring inputs of the relay (PF=1).
•
Adjust the angle between voltage and current (current pointer lagging) with an abrupt change to
PF = 0.707 (45°) lagging.
•
Measure the tripping delay at the output of the relay. Compare the measured tripping time to the selected trip
time.
Successful test result:
The measured total tripping delays, threshold, and reset values correspond with those values specified in the adjust-
ment list. Permissible deviations/tolerances can be found the Technical Data section.
RT - Remote Trip
Available elements:
Remote Trip
All
element
s of the
Remote Trip are identically structured.
By means of these elements, the protective device can detect and execute pickups and trips that are issued by other
external devices. This can be helpful, for logging purposes, if the other device is not equipped with an event or
waveform recorder. This might also be helpful if the other device has no communication (SCADA) interface.
