The electric equipment of the recently building is established in underground of the building, it is the actual condition where the immediacy countermeasure preparation which is special regarding an electric equipment is deficient. The dissertation which it sees the case where the mold transformer which is established in the underground enclosure will be flooded minimizes the damage regarding the 1st disaster it could occur and a 2nd disaster in the test Book of Psalms to select the mold transformer which at fundamental phase of the research for is established on th actual underground enclosure, it analyzed the surface discharge voltage which it follows in distance and the electric current corrugated back. It appears with the fact that the recording surface discharge voltage where the analysis result electrode for interval will become larger increases, peek of discharge current highly there is a possibility of knowing the burden. Also, it caused by with increase of the surface discharge hour and the recording discharge hour when the interval of electrode for will become larger to increase also the insulation scandal damage will be augmented with the fact that it is thought.
