| Summary: | 碩士 === 國立勤益科技大學 === 電機工程系 === 106 === This study is to analyse and preventtheelectricity stealing for overhead distribution lines. The overhead distribution lines that provide stable power supply to users is the end line of power company power system. Because the materials used in overhead distribution lines are composed of copper, aluminum and steel, they are often stolen effortlessly by thieves for exchanging into money. As soon as stealing event happens, power failure will occur in the area of wire stolen and result in the loss of electricity income as well. Therefore, it is an important internal issues for power company to prevent electricity stealing. This study aims at analyzing the electricity stealing methods with practical cases, elucidating the loss calculation about distribution wires, then judging whether there is electricity stealing in the area by the analyzed loss of electricity supply. Hopefully, it not only prevents the electricity stealing of the thieves but also maintains the stable power supply.
