Investigation of power factor on harmonic effect due to types of voltage source

Abstract

This paper discussed about power factor on harmonic effect due to types of voltage source. Usually, the voltage source is sinusoidal. But in actually, the condition of the load is has voltage sources through the elements where the output voltage of element as input to load is did not pure sinusoidal, for example at PCC between transformer and linear load and nonlinear load. The research has done with Schhafner Power Quality Analyzer. The research was focused to power factor (p.f.), THD, and harmonic energy losses cost from measurement where load is Induction motor and ASD. As voltage source in this research are sine wave and combinations of 3rd, 5th and 7th harmonic order like harmonic 313, and harmonic 357.
