ANALISIS PENGUJIAN ARUS BOCOR LINE POST INSULATOR 70 kV YANG TERKONTAMINASI POLUTAN INDUSTRI
Abstract: Failure of
Insulators of ‘Line Post Insulator 70 kV type’ usually caused by many factors,
such as the leakage current on contaminated insulator surfaces. This leakage
current will cause interference with the electrical energy distribution system.
This study reported the results of testing the leakage current on insulator 70
kV Line Post Insulator type performed on
high-voltage laboratory Ujung Pandang State Polytecchnics. Based on testing,
the maximum leakage current value obtained in wet conditions polluted with
spraying of pollutants ESDD = 3.2 mg/cm2 and NSDD = 0.08 mg/cm2 with a value of leakage current
of 7.4 mA at an applied voltage of 22 kV, this can result in flashover.
