Protection and Logic Functions
Global Settings (SET G Command)
With these example settings, the relay will enter daylight-saving time on the
last Sunday in March at 0200 h, and leave daylight-saving time on the third
Wednesday in October at 0300 h. The relay asserts Relay Word bit DST when
DST is active.
When an IRIG-B time source is being used, the relay time follows the IRIG-B
time, including daylight-saving time start and end, as commanded by the time
source. If there is a discrepancy between the daylight-saving time settings and
the received IRIG-B signal, the relay follows the IRIG-B signal.
When using IEEE C37.118 compliant IRIG-B signals (e.g., Global setting
IRIGC = C37.118), the relay automatically populates the DST Relay Word bit,
regardless of the daylight-saving time settings.
When using regular IRIG-B signals (e.g., Global setting IRIGC = NONE), the
relay only populates the DST Relay Word bit of the daylight-saving time
settings are properly configured.
Simple Network Time
Protocol (SNTP)
The SEL-700G Port 1 (Ethernet Port) supports the SNTP Client protocol. See
Section 7: Communications, Simple Network Time Protocol (SNTP) on
page 7.12 for a description and Table 7.4 for the settings.
