This paper presents a comparison between the Direct-On-Line, Star-Delta, and Auto-transformer induction motor starting method in terms of power quality. The purpose of this research is to identify the most reliable and practical starting method with fewer power quality problems. These three basic starting methods which differ in their respective wiring connections are the most applicable and widely-used starting methods in the industrial area for its economic reasons. This research was produced by analyzing the existing power quality events during motor starting by using the Fluke Power Quality Analyzer to capture the waveforms of the events. Hence, the most suitable and applicable starting method which causes the least severe power quality event can be identified
