WATTMETRIC GROUND FAULT 1(2)
The wattmetric zero-sequence directional element responds to power derived from zero-sequence voltage and current in a
direction specified by the element characteristic angle. The angle can be set within all four quadrants and the power can be
active or reactive. Therefore, the element may be used to sense either forward or reverse ground faults in either inductive,
capacitive or resistive networks. The inverse time characteristic allows time coordination of elements across the network.
Typical applications include ground fault protection in solidly grounded transmission networks, grounded/ungrounded/resis-
tor-grounded/resonant-grounded distribution networks, or for directionalizing other non-directional ground elements.
•
WATTMETRIC GND FLT 1 VOLT
: The element uses neutral voltage (that is, three times the zero-sequence voltage).
This setting allows selecting between the internally calculated neutral voltage, or externally supplied voltage (broken
delta VT connected to the auxiliary channel bank of the relay). When the latter selection is made, the auxiliary channel
must be identified by the user as a neutral voltage under the VT bank settings. This element will operate only if the aux-
iliary voltage is configured as neutral.
