Abstract: Analysis was made to the generation mechanism of transformer residual magnetism and the harm of residual magnetism to the operation of equipment and according to its features, a set of transformer degaussing system based on manual controlled group software (MCGS) was designed. The practical test carried out verification for degaussing effect of the degaussing system. The result shows that the system has effectively eliminated unfavorable impacts of residual magnetism on protection device of transformer and equipment at primary side, which avoided transformers becoming harmonic sources in the grid and raised power supply quality of power supply system.
Key words: transformer; residual magnetism; degaussing
