A research on the actual condition of the underground manhole in domestic

국내 저압지중함의 현장실태조사

The increased use of underground power distribution as opposed to overhead lines contributes to the aesthetics of the downtown areas. But there is an inherent risk of accidental electrocution should there be damage to the insulation of the cable because of heavy rain. Should a pedestrian make contact with this cable indirectly, via a man hole cover, electrocution could result. In this paper, we analyse weaknesses in this low-voltage manhole and propose improvements.
