NOTE
There is no indication for tripping of the grounding stages. If you need information link the internal pickup
signal with the OFF command of the stage, e.g, 67-1 PU N and 67(N)-B2 TRIP
Behavior during Measuring Voltage Failure
An element-specific parameter, e.g. 67(N)-B1 on FFM allows you to define how the directional overcurrent
protection acts when the measuring voltage fails. The overcurrent protection then works either Non-Direc-
tional or it is BLOCKED.
Setting Notes
General
The setting notes described in the following apply to non-directional and directional overcurrent protection.
Operating Modes
You set the operating mode of the overcurrent protection elements specifically for each element. The setting
applies collectively to the corresponding phase and ground element.
