2/27D, 59N-1, 59N-2 and of the external trip, shown as a percentage
of the set operate time, or of the calculated operate time at IDMT
characteristic. A value other than zero indicates that the
corresponding element has picked up whereas a value which is 100%
of the set or calculated operate time indicates that the operate time of
the element has elapsed, that is, the element has tripped. If the
operate time of a element has elapsed but the element is blocked, the
value is 99% of the set or calculated operate time.
Time stamp for the event. The time when the collected data was

stored. The time stamp is displayed in two registers, one including the
date expressed as yy-mm-dd, and the other including the time
expressed as HH.MM;SS.sss.

EVENT 5 Same as EVENT 1.
Number of The number of times each protection element 59P-1, 59P-2/47, 27P-1,
pickups 27P-2/27D, 59N-1, 59N-2 has picked up, counting up to 999.
Number of Number of trips:
