Possible fault Cause Remedy
Effective power too large or too
small. The programmed current transformer transfor-
mation ratio is incorrect. Read out and program the current transformer
transformation ratio at the current transformer
The current path is assigned to the wrong
voltage path. Check connection and correct if necessary.
The programmed voltage transformer transfor-
mation ratio is incorrect. Read out and program the voltage transformer
transformation ratio at the voltage transformer.
