Power generation is a business that both satisfy industrial and consumer needs. Power generation technologies had emerged from conventional power plant which is denoted by conventional steam plant and evolved all the way to nuclear plant. While mechanical arrangements are usually unique and differ from a type of power plant compared to another, electrical assemblies are almost the same. Much anticipating factor is sizing of the electrical equipment. Among fundamental equipment that is a must have in a power plant is an electrical generator. In principle, generator is crucial equipment that needs a proper maintenance in order to produce a steady output stream. The objective of this study is to investigate partial discharge characteristics of 3 unit generators stator winding at Tanjung Bin Power Plant, Johor, Malaysia. We will compare the partial discharge characteristics of unit 10, 20 and 30 generators stator winding, respectively. Software designed by Iris LP will be used throughout these processes. The software-PDView will demonstrate graphical view of the partial discharge occurrence in the generator stator winding. Compiled data will be analyzed using Microsoft Excel in order to establish an evaluation of the generator stator winding. The analyzed results showed that all generators are in good condition
