Figure 228: Non-directional ground-fault protection
Two stages are offered for directional ground-fault protection. By default the stages
DEFHPDEF1_67/50N-1 and DEFHPDEF2_67/50N-2 are blocked by the fuse failure
detection and the polarization choice is set to negative sequence voltage. Also by default,
these two functions are also not blocked by a cold load situation.
The polarization should never be set to “measured” as there is no
dedicated Vg input for this configuration. Setting polarization to Vg will
result in a settings error.
