Total Harmonic Distortion at Fault in RLC Load [PDF]

Indonesian Journal of Electrical Engineering and Computer Science, 2016
<p>This paper focuses on the calculation of total harmonic distortion (THD) at various fault situations in case of RLC load. The faults are created by introducing heavy impedance of 1000 ohm, by blowing off the gate pulse at one of the terminals of the mosfet, and by introducing a line to ground fault. The Matlab based simulation has been done to

Precision of the Sinefitting-Based Total Harmonic Distortion Estimator [PDF]

Metrology and Measurement Systems, 2016
Abstract An analytical expression for the standard deviation of Total Harmonic Distortion (THD) estimation is derived. It applies to the case where the estimator uses sine fitting. It is shown that, in common circumstances, it is inversely proportional to the actual value of THD, the signal-to-noise ratio and the square root of the number of ...
