Phase C Voltage (Blue) and Phase C current (Yellow) are in phase and the same
polarity.

Note:
The example VLine & ILine Waveform Plot screens apply to rectifier loads only. For low
power factor loads, the VLine & ILine waveform screen will appear different.
The table below shows what the VLine & ILine Waveform Plot Sub Screen would look like with
various connection errors present in the system.
