How do you calculate harmonic voltage distortion?
The individual harmonic voltage distortion levels can be established by performing this calculation for the p.u. current associated with each harmonic number.
The Voltage Total Harmonic Distortion [THD] is then calculated by establishing the square root of the sum of the squares of these individual Voltage harmonics.How do you find the third harmonic current?
This means if we consider a given 50 Hz fundamental waveform, the second harmonic frequency would be 100 Hz (2 x 50 Hz), a third harmonic would be at 150 Hz (3 x 50 Hz), and so on.
Similarly, if the given fundamental waveform changes to 60 Hz, the second harmonic would be at 120 Hz.Harmonic currents and the electrical distribution system
Harmonic currents flow in a circuit at multiples of the fundamental 60 hertz (Hz) frequency.
For example, current flowing in a circuit at 180 Hz is the third harmonic (60 Hz multiplied by 3).
How do you calculate the THD?
If you wanted to calculate the THD, you would take all of the harmonics in order, square them, take the square root of that total and divide by the fundamental.
