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. Keyword : Insulator, Current leakage, Flashover

Abstract

The problem in this study were: (1) how the intensity of pollution sector in the region polluted insulator, (2) how polluted insulator surface conductivity Parent substations in each region, (3) how to profile an appropriate insulators for substations with different levels of intensity of pollution sector in the region. To solve this problem pollutant sampling conducted on ceramic insulators on the channel milestone substation switchyard each region at two different points, namely at the top of the insulator and the bottom fin insulators. The results showed the intensity of pollution for every region of substation at a concentration of 0.50 g / l has a value of ESDD with dissolved heavy pollutant levels (> 0.1 mg/cm2), while the value of NSDD categorized insoluble low-level pollutants. Maximum leakage current value obtained by GI. Makale 4.73 mA, GI. Sungguminasa 4.47 mA, GI. Tello 4.60 mA, GI. Long Tallo 4.67 mA and GI. Pangkep 4.87 mA.   Keywords : Insulator, Pollutan, ESDD, NSDD
