Current harmonic distortion
WebThe harmonic distortion can be defined by using this example. When the 5V input signal is applied to the circuit, then the output signal will have only 2V voltage. It indicates the signal loses its voltage because of … WebPower Quality / By Admin. Total Harmonic Distortion or THD is an indicative measurement of power quality in electrical systems. When there is presence of harmonics in electrical power system, it will create a disturbance in electrical supply. Both voltage and current frequency can have harmonic components to create a distortion.
