1. Select the Faults | Voltage-Sag Analysis | Show 3LG Faults Solution On 1-Line Command.
TO DISPLAY 2LG FAULT VOLTAGE SAG RESULT:
1. Select the Faults | Voltage-Sag Analysis | Show 2LG Faults Solution On 1-Line Command.
TO DISPLAY 1LG FAULT VOLTAGE SAG RESULT:
1. Select the Faults | Voltage-Sag Analysis | Show 1LG Faults Solution On 1-Line Command.
TO DISPLAY LL FAULT VOLTAGE SAG RESULT:
1. Select the Faults | Voltage-Sag Analysis | Show LL Faults Solution On 1-Line Command.
OneLiner will display the voltage-sag results on the one-line diagram. Specifically, the monitored-bus voltage in per unit will be shown below each faulted bus name. The program will also paint a colored halo around each faulted bus to help you visualize its effect on the monitored bus. The more severe the voltage sag at the monitored bus caused by a fault, the darker the halo will be painted around the faulted bus.
