STATOR GROUND
Magnitudes of the third harmonic components of the machine neutral point voltage (VN), the zero-sequence voltage at the
machine terminals (V0), and in the vector sum of the neutral point voltage and zero-sequence voltage (VN + V0) are avail-
able for display. The values are calculated for a signal source specified under the stator ground settings menu.
These readings may be useful when selecting a pickup and supervision setting for the 100% stator ground and third har-
monic neutral undervoltage protection elements.
