However there are loads and devices on the system that have nonlinear characteristic which is affected both voltage and current signal and result in harmonic distortion causing poor power quality.
Thus it is used for reducing the harmonics by using the Total Harmonic Distortion (THD) method by which we gain the two voltages of the system in a reduced form and the hardware reads the voltage, frequency of the system.
In addition to THD, this harmonic distortion multimeter can compute THD+Noise and Signalto-Noise plus Distortion (SINAD).
One customer's harmonic distortion can interfere with the quality of a neighboring customer's electricity.
In addition to the adverse affects of harmonic distortion mentioned above, low power factor also results in the need to oversize all aspects of the power installation--from the UPS itself all the way back to the utility transmission level.
In the above multiple socket plug, the loads and filters are connected in different combinations and the reduction in harmonic distortion are monitored in the Matlab.
The increased in harmonic distortion causes the extra heating losses, shorter insulation life span, higher insulation stress and temperature, reduced power factor and efficiency of the electrical equipment.
The harmonic distortion for a synthesized 5 kHz sine wave was more than 100 dB below the fundamental.
Specifically targeted to communications applications, the instrument includes semi-automated routines to measure adjacent and main channel powers, as shown in Figures 1 and 2, respectively, as well as occupied bandwidth, harmonic distortion and power levels below the carrier.
This research paper presents the theoretical, simulation and empirical based harmonic distortion analysis.
The parameters that define the audio quality of a single-tone sine wave are signal-to-noise ratio (SNR), total harmonic distortion (THD), and signal-to-noise and distortion ratio (SINAD), also known as total harmonic distortion plus noise (THD+N).
