Cause Analysis and Treatment of Excessive Dielectric Loss of Main Body in Transformer Finished Product Test
In this paper,through the troubleshooting process of the excessive dielectric loss of the main body in the finished product test of a 63MVA/110kV transformer,the author finally confirms that it is caused by the quality status of the laminated wood round support rod in the middle layer of the iron core column,rather than incomplete drying or dampness of the transformer body.This provides a new idea and direction for the analysis and treatment of excessive dielectric loss in actual transformer production.
