【Abstract】 The security of transformers is significant for power transmission. The theory of online testing for transformers iron loss and copper loss is discussed in this paper. A fault diagnosis system of transformers based on DSP is presented. The design of the hardware and the software of this system is discussed in detail, and the problem of the anti-disturbance of the system is analyzed. The system experimentally meets the demands in anticipation, and one new monitoring method for ensuring transformers operating in security is provided by using this system.更多还原
