■
Reactive Power (RePwr): The reactive power or the imaginary power delivered to and temporarily stored in the reactive
(inductive or capacitive) elements of the load, measured in units of Volt-Amperes-Reactive or VAR. The application
calculates the Reactive power using the following equation:
Where, RePwr is the Reactive Power, Volt-Amperes-Reactive or VAR.
■
Power Factor (PF): It is calculated using the following equation:
Where, PF is the Power Factor.
■
Crest Factor (CF): It is the ratio of the peak voltage value of the signal to the RMS value of the signal. Use the following
equation to calculate the crest factor for the voltage and current:
Where:
VCF is the Voltage Crest Factor.
V
PK
is the peak value of the voltage.
V
RMS
is the Root Mean Square of the voltage.
Where:
ICF is the Current Crest Factor.
I
RMS
is the Root Mean Square of the current.
■
Phase Angle (σ): It is the angle (-90 to +90) whose cosine is the true power factor. Unit of Phase Angle is degrees. The
angle is positive if the Ch1 waveform (typically voltage) leads the Ch2 waveform (typically current). The angle is negative if
the Ch1 waveform lags behind the Ch2 waveform. The application calculates the phase angle using the following equation:
