Table 5.1.12.-1 Recorded data
REGISTER Data description
EVENT1
*
Phase-to-phase voltage U
ab
measured at a time of trip as a multiple of
the rated voltage, U
n
(VT). The same applies to phase-to-phase
voltages U
bc
and U
ca
.
*
Residual voltage U
n
measured at a time of trip as a percentage of the
rated voltage U
n
(VT).
*
Maximum voltage value of the phase-to-phase voltages during the last
fault conditions in the network, measured as a multiple of the rated
voltage U
n
(VT)
* Minimum voltage value of the phase-to-phase voltages during the last
fault conditions in the network, measured as a multiple of the rated
voltage U
n
(VT).
*
Maximum voltage value of the negative phase-sequence voltage
during the last fault conditions in the network, measured as a multiple
of the rated voltage U
n
(VT). If element 59P-2 is not based on negative
phase-sequence voltage U
2
, dashes are shown on the LCD and "
999
"
when read via serial communication.
*
Minimum voltage value of the positive phase-sequence voltage during
the last fault conditions in the network, measured as a multiple of the
rated voltage U
n
(VT). If element 27P-2 is not based on positive
phase-sequence voltage U
1
, dashes are shown on the LCD and "999"
when read via serial communication.
* Maximum voltage value of the residual voltage U
n
during the last fault
conditions in the network, measured as a percentage of the rated
voltage U
n
(VT).
*
Duration of the last pickup of elements 59P-1, 59P-2/47, 27P-1, 27P-
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 2 Same as EVENT 1.
EVENT 3 Same as EVENT 1.
EVENT 4 Same as EVENT 1.
EVENT 5 Same as EVENT 1.
Number of
pickups The number of times each protection element 59P-1, 59P-2/47, 27P-1,
27P-2/27D, 59N-1, 59N-2 has picked up, counting up to 999.
Number of
trips Number of trips:
*
Overvoltage elements 59P-1, 59P-2 and 47
*
Undervoltage elements 27P-1, 27P-2 and 27D
*
Residual overvoltage elements 59N-1 and 29N-2
* External trip
When the counters reach their maximum values (65535), they roll over.
