7.3 User Inputs

This section explains the list of user input options available on custom dashboard window of data visualizer for demonstrating phase reversal and phase loss faults.

• Recover three-phase supply from faults:
  • Select RC to recover the three-phase signal from either the phase loss fault or the phase reversal fault.
• Insert phase-loss fault on L1 phase:
  • Select L1 to emulate L1 phase-loss fault on three-phase signal, which disables the L1 phase out of the three-phase signal.
• Insert phase-loss fault on L2 phase:
  • Select L2 to emulate L2 phase-loss fault on three-phase signal, which disables the L2 phase out of the three-phase signal.
• Insert phase-loss fault on L3 phase:
  • Select L3 to emulate L3 phase-loss fault on three-phase signal, which disables the L3 phase out of the three-phase signal.
• Insert phase-reversal fault:
  • Select option PR to emulate the phase-reversal fault on three-phase signal, which changes the sequence of the three-phase signal to L1-L3-L2.

Figure 7-13 shows the user input options for phase sequence detection demonstration.
