 IEC 61850
 GOOSE ANALOGS
The G30 Generator Protection System is provided with optional IEC 61850 communications capability.
This feature is specified as a software option at the time of ordering. Refer to the Ordering section of chap-
ter 2 for additional details.
The IEC 61850 GGIO3 analog input data points are displayed in this menu. The GGIO3 analog data values are received
via IEC 61850 GOOSE messages sent from other devices.

The effective operating quantities of the sensitive directional power elements are displayed here. The display may be useful
to calibrate the feature by compensating the angular errors of the CTs and VTs with the use of the
settings.

 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 third harmonic neutral undervoltage
protection element.
