Harmonic Assessment Based Adjusted Current Total Harmonic Distortion
The Journal of Engineering, 2016 Power systems suffer from harmonic distortion and extra ohmic losses associated with them. Moreover, all harmonic frequencies are mostly assumed to have the same effect on the system losses. However, the frequency‐dependency of the resistances should be taken into account, so that the apparent power and the power factor have to ...

Total Harmonic Distortion at Fault in RLC Load
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
