		abstract={In the concrete substation of the main components of the installation of transformers and switching equipment / protection, arranged in spil building designed, built and functioned with the construction of stone and concrete pairs of construction. This construction is intended to meet the best requirements for electrical safety. In medium voltage connectors 20 kV substation pair distribution in consisting of several types is cubicles. Cubicle 20kV is a set of electrical equipment installed in distribution substation that serves as a divider, breaker , connectors , controllers and system power supply protection 20 kV. Working voltage PLN in distribution phase one side was 11.56 kV. With the increasing voltage then arises the problems of insulating equipment in cubicle. The problems that often occurs in cubicles when this is corona, a phenomenon that occurs in the air around conductors or conductor ionized. Of the process there was a release of the charge which can lead to failure of the insulation on the air. As a result the fatal because it can cause phsycal damage on the equipment in the cubicles, cause audio noise and power loss. Distribution substation T241 has RH=80%, Ev=3.94 kV and Ploss 3.88 kW while distribution substation K245 have RH=86%, Ev=4.37 kV and Ploss 3.45 kW substation where T241 and K245 Ev nya < 11,56 kV, then kubikel hit by corona. For substation T407 has RH=45%, Ev=18.34 kV, because Ev > 11,56 kV then corona no exsposed to cubicle.}
