碩士 === 聖約翰科技大學 === 自動化及機電整合研究所 === 98 === The main purpose of this thesis is how to install the equipments which are generator inspection facilities and analysis insulation orientation in power station. The end user can through this thesis to understand and realize the partial discharge detection facilities status easily. Three major sections are discussed in this thesis that including 1. What is partial discharge? 2. How to choose the proper equipments and instruments for partial discharge detection for generator? 3. How to judge and determine the state is pass the criteria or not? Firstly, the explanation of discharge states are divided into several affect factors which are thermal, electronic, warm up, and environment pollutions. Secondly, the description of advantages, benefits and inferiorities, disadvantages on monitoring, testing in line mode and off-line which also included the equipment chosen. Besides, it also deliberate how to choose the coupler, what is the proper time to use different installation methods, and user can comprehend which one is the best choice. Finally, it is important to process the trouble-shooting without the help of professional operators. Therefore, this thesis which is chosen the practical experiment and software analysis to let the user has a clear picture to understand how to determine what the facilities status and when is the right time to execute the repair, maintain or replace the generator coil.
