Abstract :
This test aims to see the effect of water contaminants on the performance of transformer oil insulators, with the isolator oil testing method given super O2 type water contaminants and using the BAUR Oil Tester DPA(Discharge Partial Arching) test equipment where the standard test equipment used is IEC 60156, and the standard translucent voltage value in insulating oil based on SPLN 49-1: 1982 oil has a penetrating voltage value of ?30kV / 2.5mm. In the distilled water contaminants given by 1ml, a decrease in the value of the penetrating voltage of 15.4kV or 31.5% was obtained, while in the number of contaminants given as much as 2ml to 10ml the value of the resulting penetrating voltage decreased to 12,7kV. The value of the penetrating voltage obtained in the test using super O2 contaminants obtained a decrease in value of up to 68%, the more water applied to the oil the more the value of the penetrating voltage and the dielectric in the insulating oil decreased.
