EDR-5000
IM02602007E
Commissioning: Vector Surge 78V
Object to be tested:
All frequency protection stages that are projected as vector surge (78V).
Necessary means:
Three-phase voltage source that can generate a definite step (sudden change) of the voltage pointers (phase
shift).
Procedure:
Testing the threshold values
Apply a vector surge (sudden change) that is 1.5 times the setting value (example: if the setting value is 10°
apply 15°).
Successful test result:
Permissible deviations/tolerances and dropout ratio can be taken from the Technical Data.
