This paper discussed about relationship of ASD and
types of voltage source on harmonic characteristics.
Usually, the voltage source is sinusoidal. But in
actually, the condition of the load is it has voltage
sources through the elements where the output voltage
of element as input to load is did not pure sinusoidal,
for example at Point at Commom Coupling (PCC)
between transformer and linear load and nonlinear
load. The research has done with Schhafner Power
Quality Analyzer. The research was focused to Cress
Factor (C.F.), Total Harmonic Distortion (THD), and
harmonic energy losses cost from measurement, where
load is the induction motor with and without ASD. As
voltage source in this research are sine wave, square
wave and combinations of 3rd, 5th and 7th harmonic
order like harmonic 35, harmonic 37, and harmonic
57.
