This presentation introduces the challenges of upgrading the electrical insulation of Fuji Electric oil-immersed transformers. Among them, an example of analysis approach using JMAG CB option will be introduce.
The following will be mainly described.
・Analysis of electric field distribution in conventional oil space
・Comparison of current analysis with boundary element method software
・Analysis example of oil space withstand voltage based on highly accurate electric field distribution
・Points for analysis
