Investigation of influence of voltage source type on harmonic characteristics

This paper discussed about influence of voltage source types on harmonic characteristics. 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. To describe the harmonic characteristic due to types of voltage source will shown as IHD, p.f., THD, and harmonic energy losses cost from measurement. As voltage source in this research are sine wave and combinations of 3^rd, 5^th and 7^th harmonic order, and square waveform are create by means of Schhafner Power Quality Analyzer.
