Clock function
Clock function (or time function) provides the time information for recording upon occurrence
of the fault; it includes a synchronization function when the reference clock is available out of
the IED. The clock is operated referring the Coordinated Universal Time (UTC‡) when the
UTC is selected; the clock can run in accordance with the user's time zone and summer
time(DST)† by referring the UTC when the time zone and the DST are set. The explanation is
also found in Chapter
†Note: In other words, it is called "daylight saving time (DST)". For setting, see Chap.
5.8.5.
‡Note: For example, the Internet and World Wide Web standards run in the UTC. For
more information, see Chap. 5.8.4.
Clock setting
5.8.1
The user can set the time using the time sub-menu as shown in Figure 5.8-1. The user also can
set the time using the GR-TIEMS†.
†Note: Make the calibration the when the clock is set using the GR-TIMES. This is
because the transmission time is required from the PC to the IED.
Selection of date and time formats
