This menu contains user angle and magnitude calibration data for the phasor measurement unit (PMU). This data is com-
bined with the factory adjustments to shift the phasors for better accuracy.
• PMU 1 VA... IG CALIBRATION ANGLE: These settings recognize applications with protection class voltage and cur-
rent sources, and allow the user to calibrate each channel (four voltages and four currents) individually to offset errors
introduced by VTs, CTs, and cabling. The setting values are effectively added to the measured angles. Therefore, enter
a positive correction of the secondary signal lags the true signal; and negative value if the secondary signal leads the
true signal.
