TREATMENT OLI TRAFO TERHADAP PENINGKATAN TEGANGAN TEMBUS PADA TRAFO DISTRIBUSI KA 756 DI BY PASS NGURAH RAI

Abstract

The transformer is an electrical apparatus that is included in the classification of static electricity machine and serves to channel the energy / power from high voltage to low voltage or vice versa, with the same frequency. Transformer oil, according to the standard test PLN (SPLN) 49-1/1992 method IEC 158 and 296 shall have a minimum insulation resistance of 30 kV / 2.5 mm. This causes the decrease in insulation resistance not optimal power is supplied to the customer. Also can cause fatal damage to the transformer itself as the occurrence of a short circuit causing the transformer to explode. Therefore, to maintain performance or life time of the transformer itself needs to be treated at least once a year. Men-oil treatment is that efforts should be made to ensure that prisoners are permitted insulation standards and transformer can operate optimally.
