Measuring-Voltage Failure Detection
Setting Values
3ph.fail. - VA,VB,VC <
3ph.fail. - phs.curr.release 1 A @ 50 and100 Irated
3ph.fail. - phs.curr. jump
Asym.fail. - time delay
SO 3ph.fail. - time delay
Dropout
The larger dropout differential (= | pickup value – dropout threshold |) of the following 2 criteria
is used:
Dropout differential derived from the parameter Dropout ratio
If this parameter is not available, a dropout ratio of 95 % applies to the current threshold value and a dropout
ratio of 105 % applies to the voltage threshold value.
Minimum absolute dropout differential
