Abstract

This paper discussed four different no-electric methods for diagnosis and troubleshooting of the large power transformers, including electron microscopy, infrared thermograph (IRT), ICP plasma emission spectrum and biological technology used for oil analysis. Practice concluded that these approaches were effective in identifying the specific faults in the transformer tanks. Successful application of these approaches also showed that interdisciplinary collaboration is a good path to resolve complex technical problems on site
