Why is the Theoretical Calculated Power Factor and Phase Angle Different Than the Measured Values?
When measuring input signals of distorted waves, signals that are DC-offset or signals that include superimposed harmonic components, will result in different values for power factor and phase angle than those expected w...

When Measuring the Balanced Three-Phase Load and Displaying the Waveform, the Phase Angle of the Voltage Across Each Input Element Does Not Equal 120 Degrees
In the three-phase three-wire, or 3V3A wiring scheme, the phase angle of voltage between each input element is 60 degrees because it is the line to line voltage that is measured. Please download and refer to the attache...
