MEASURING THE VOLTAGE/CURRENT RMS VALUE AND POWER USING
QUASI-SYNCHRONOUS SAMPLING ALGORITHM
From Equation C-11, a periodic voltage can be expressed as:
EQUATION C-25:
So the voltage fundamental and the voltage of each harmonic can be expressed as:
EQUATION C-26:
From Equation C-25, the fundamental voltage and voltage of each harmonic can also
be expressed as:
EQUATION C-27:
Where:
EQUATION C-28:
EQUATION C-29:
The voltage RMS value of each harmonic, then can be expressed as shown in
Equation C-31 with its initial phase angle shown in Equation C-29.
