Protective Elements
Testing the trip delay (PF Trigger: Example = 0.86 lagging)
•
Feed 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
parameterized.
Successful test result
The measured total tripping delays, threshold and reset values correspond with those values, specified in the
adjustment list. Permissible deviations/tolerances can be found under Technical Data.
