Abstract

With the recurring stability issues within the university power distribution system, an unusual cause of electrical equipment failures has arise in the form of hot spots. Hotspots, created through poor load scheduling, loose connections, rust, and ageing of electrical equipment, severely reduces the lifespan of any equipment and may damage the system as a whole. In this study, electrical hotspots was determined by inspection of the overhead distribution system in the university, which included transmission line conductors, pole pins and insulators, fuse link cut outs, transformer bushings, transformers, and reclosers. By infrared thermographic surveying, using a Fluke® Ti32 infrared camera, overheating was found on different electrical equipment and was analyzed using the delta-T and the ambient temperature criteria. Corrective measures were then suggested to be able to improve the current state of the system such as: increasing the rating of the electrical equipment, addition of another transformer, or performing maintenance check on these equipment in question. These corrections are then verified by performing load flow analysis using Synergi® & Solver Engineering Analysis Software where transformer load data were fed to. By these series of inspection and analysis, a better system was achieved by eliminating electrical hotspots in the distribution system of UPLB.
