④ Phase of event: “a” denotes phase A, “b” denotes phase B, “c” denotes phase
C.
⑤ The time of the event occur.
See in fig 3.5.3.2: the time of the event occurs is 2007-11-27 13:21:59 253ms
You can view all the SOE events pressing “ ” or “ ”.
3.5.4. Inquiry the electrical parameters of maximum and minimum operating
presentation
After entering the electrical parameters of the maximum and minimum mode,
press or button to page up and down to view; press button to view
the value of a electrical parameter and the time of occurrence, minimum and
maximum occurrence time are flashing several second. The time display mode is
“year-month-day” and “hour: minute: second” alternating
displayed. The current statistical data viewed are all from
last statistical interval.
