Fault Reports - GE L90 Instruction Manual

5 SETTINGS
If the L90 channel asymmetry function is enabled, the IRIG-B input must be connected to the GPS receiver
and the proper receiver signal type assigned.
NOTE
The date and time can be synchronized a known time base and to other relays using an IRIG-B signal. It has the same
accuracy as an electronic watch, approximately ±1 minute per month. If an IRIG-B signal is connected to the relay, only the
current year needs to be entered. See the
The
REAL TIME CLOCK EVENTS
The
LOCAL TIME OFFSET FROM UTC
(Greenwich Mean Time) in hours. This setting has two uses. When the L90 is time synchronized with IRIG-B, or has no per-
manent time synchronization, the offset is used to calculate UTC time for IEC 61850 features. When the L90 is time syn-
chronized with SNTP, the offset is used to determine the local time for the L90 clock, since SNTP provides UTC time.
The daylight savings time (DST) settings can be used to allow the L90 clock can follow the DST rules of the local time zone.
Note that when IRIG-B time synchronization is active, the DST settings are ignored. The DST settings are used when the
L90 is synchronized with SNTP, or when neither SNTP nor IRIG-B is used.
Only timestamps in the event recorder and communications protocols are affected by the daylight savings time set-
tings. The reported real-time clock value does not change.
