4.7.1.1 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.

order.
Common for P126 & P127 are:
tIe>, tIe>>, tIe>>>, tPe/IeCos>, tPe/IeCos>>, Trip
tUe>>>>, tI>, tI>>, tI>>>, tI<, tI2>, tI2>>,
tI2>>>, Thermal q, Brkn. Cond, Aux 1, Aux 2, EQU

Only valid for P127:
tU>, tU>>, tU<, tU<<
Magnitude
1200 A
Displays the magnitude value of the fault: Voltage,
current, earth power. The value is based on the
amplitude at 50 or 60 Hz.
