Dropout
The greater dropout differential (= | pickup value – dropout value |) of the following 2 criteria
applies:
Dropout
Minimum absolute dropout differential
Protection-class current transformer
Instrument current transformer
Reset of the Integration Timer
Instantaneous
Disk emulation
Direction Determination
Type
Forward range
Dropout differential forward/reverse range
Directional sensitivity
Times
Operate time with time delay = 0 ms
Extension of the operate time during operation with
transformer inrush-current detection
63 If you have selected the method of measurement = RMS value, do not set the threshold value under 0.1 l
64 OOT (Output Operating Time): additional delay of the output medium used, for example 5 ms with fast relays
