 FAULT REPORT 1

The latest 15 fault reports can be stored. The most recent fault location calculation (when applicable) is displayed in this
menu, along with the date and time stamp of the event which triggered the calculation. See the
menu for assigning the source and trigger for fault calculations. See the
SETUP  FAULT REPORTS
menu for manual clearing of the fault reports and to the
RECORDS
menu for automated clearing of the fault reports.
Where VA, VB, VC are phase voltage phasors in secondary volts; IA, IB, IC are current phasors in secondary amps, I0 is the
zero sequence current phasors in secondary amps; and IG is the ground current from the parallel line scaled to the source
phase CT in secondary amps. Z0/Z1 is the zero sequence impedance to positive sequence impedance ratio, and Z0M/Z1 is
mutual zero sequence impedance to positive sequence impedance ratio.
VTs of the
