Figure 176: Admittance-based ground-fault protection function
Phase discontinuity protection PDNSPTOC1_46PD protects for interruptions in the
normal three-phase load supply, for example, in downed conductor situations. The
function is blocked in case of detection of a failure in secondary circuit of voltage
transformer.
