IDMT: Factor kt,neg PSx
072 054 073 054 074 054 075 054
Fig. 3-88
Setting for factor kt,neg of the starting characteristic (negative-sequence
current system).
IDMT: Min.trip time negPSx

Fig. 3-88
Setting for the minimum trip time (negative-sequence current system). As a
rule, this value should be set as for the first DTOC stage (I>).

Fig. 3-88
Setting for the holding time for intermittent short circuits (negative-sequence
current system).
IDMT: Release neg. PSx
072 060 073 060 074 060 075 060

Fig. 3-90
Setting for the reference current in dynamic mode (residual current system).
This operate value is effective only while the timer stage MAIN: Hold-
