The UR device maintains two times: local time and Universal Coordinated Time (UTC). Local time can be provided by IRIG-
B signals. UTC time is provided by SNTP servers.
The real-time clock (RTC) and time stamps reported in historical records and communication protocols can be incorrect if
the Local Time settings are not configured properly.
See the IRIG-B section in the Installation chapter for guidance on these settings when using an IRIG-B source that sets the
IRIG-B control bits according to IEEE Std 1344-1995.
The
LOCAL TIME OFFSET FROM UTC
setting is used to specify the local time zone offset from UTC (Greenwich Mean Time) in
hours. Time zones in the eastern hemisphere have positive values; time zones in the western hemisphere have negative
values. A value of zero causes the relay to use UTC for local time. This setting has two uses. When the system RTC is syn-
chronized with a communications protocol providing only local time or it is free-running, the offset setting is used to calcu-
late UTC from the local time these provide. When the RTC is synchronized with a communications protocol providing only
UTC (such as PTP or SNTP), the time offset setting is used to determine local time from the UTC provided. PTP
ALTERNATE_TIME_OFFSET_INDICATOR TLVs are not used to calculate local time.
The
DAYLIGHT SAVINGS TIME (DST)
settings can be used to allow the relay to follow the DST rules of the local time zone.
Note that when IRIG-B time synchronization is active, the local time in the IRIG-B signal contains any daylight savings time
offset and so the DST settings are ignored.
5.2.7 USER-PROGRAMMABLE FAULT REPORT
PATH: SETTINGS
PRODUCT SETUP
USER-PROGRAMMABLE FAULT REPORT
USER-PROGRAMMABLE FAULT REPORT 1(2)
When enabled, this function monitors the pre-fault trigger. The pre-fault data are stored in the memory for prospective cre-
ation of the fault report on the rising edge of the pre-fault trigger. The element waits for the fault trigger as long as the pre-
fault trigger is asserted, but not shorter than 1 second. When the fault trigger occurs, the fault data is stored and the com-
plete report is created. If the fault trigger does not occur within 1 second after the pre-fault trigger drops out, the element
resets and no record is created.
The user programmable record contains the following information: the user-programmed relay name, detailed firmware
revision (7.2x, for example) and relay model (T60), the date and time of trigger, the name of pre-fault trigger (a specific
FlexLogic operand), the name of fault trigger (a specific FlexLogic operand), the active setting group at pre-fault trigger, the
active setting group at fault trigger, pre-fault values of all programmed analog channels (one cycle before pre-fault trigger),
and fault values of all programmed analog channels (at the fault trigger).
The report includes fault duration times for each of the breakers (created by the breaker arcing current feature). To include
fault duration times in the fault report, the user must enable and configure breaker arcing current feature for each of the
breakers. Fault duration is reported on a per-phase basis.
