【Abstract】 Diagnosis of power transformer abnormality is important for power system reliability. The principle and usual methods for transfonner fault diagnosis, and the construction, mechanism and performance of TFDES(an expert system for power transformer fault diagnosis) arc described in this paper. The results of preliminary tests show that the system has reasonable construction and correct inference, and can effectively detect incipient faults of transformers in service.更多还原
