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
COMMANDS
SET DATE AND TIME
menu to manually set the relay clock.
The
REAL TIME CLOCK EVENTS
setting allows changes to the date and/or time to be captured in the event record.
The
LOCAL TIME OFFSET FROM UTC
setting is used to specify the local time zone offset from Universal Coordinated Time
(Greenwich Mean Time) in hours. This setting has two uses. When the T60 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 T60 is time syn-
chronized with SNTP, the offset is used to determine the local time for the T60 clock, since SNTP provides UTC time.
The daylight savings time (DST) settings can be used to allow the T60 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
T60 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.
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 (5.9x, 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 trig-
ger, 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.
Each fault report is stored as a file to a maximum capacity of ten files. An eleventh trigger overwrites the oldest file. The
EnerVista UR Setup software is required to view all captured data. A
FAULT RPT TRIG
event is automatically created when
the report is triggered.
