IEC 61850 GOOSE ANALOGS
The G60 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 protocol features are not available if CPU type E is ordered.
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.

SENSITIVE DIRECTIONAL POWER
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
RCA
and
CALIBRATION
settings.
