Sensitive Directional Power; Stator Ground; Sub-Harmonic Stator Ground; Field Ground - GE G60 Instruction Manual

CHAPTER 6: ACTUAL VALUES
The G60 is provided with optional GOOSE communications capability. This feature is specified as a software
option at the time of ordering. See the Order Codes section of chapter 2 for details.
The RxGOOSE Analog values display in this menu. The RxGOOSE Analog values are received via IEC 61850 GOOSE
messages sent from other devices.

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
available for display. The values are calculated for a signal source specified under the
These readings can be useful when selecting a pickup and supervision setting for the 100% stator ground and third
harmonic neutral undervoltage protection elements.
