4.8.1.1 Submenu Fault Record for P126 & P127
The Fault Record submenu makes it possible to read up to five stored fault records, that
occurred when programmed thresholds where exceeded.
The fault records are generated by the operation of trip relay RL1.
NOTE: All measurement magnitude values refer to the transformer primary
side.

Fault Time
13:05:23
Displays the time when the fault was recorded. The format
of the time is hh:mm:ss.
In this example the fault was recorded at 1:05:23 pm.
Fault Date
12/11/01
Displays the date when the fault was recorded. The format
of the Date is DD/MM/YY.
In this example, the fault was recorded on November 12th
2001.
Active Set Group
1
Displays the active setting group (1 or 2).
Faulted Phase
PHASE
A
Displays the phase, where a fault occurred, for the chosen
fault record. (NONE, PHASE A, B, C, EARTH)
Threshold

A
Displays the magnitude value of the fault: Voltage, current,
earth power. The value is based on the amplitude at 50 or
60 Hz.
IA Magnitude
1200
A
Displays the magnitude value of the phase A current at the
time of the fault.
IB Magnitude
1200
A
Displays the magnitude value of the phase B current at the
time of the fault.
IC Magnitude
1280
A
Displays the magnitude value of the phase C current at the
time of the fault.
IN Magnitude
103
A
Displays the magnitude value of the earth current at the
time of the fault.
VAB Magnitude
10
KV
Only P127
Displays the magnitude value of the phase A to phase B
voltage at the time of the fault.
VBC Magnitude
10
KV
Only P127
Displays the magnitude value of the phase B to phase C
voltage at the time of the fault.
