Effect of Industrial Pollution on Different Types of High Voltage Insulators
Keywords:
Porcelain insulator, silicon rubber insulator, flashover voltage, pollution insulatorAbstract
High voltage insulators is essential part of the high voltage electric power transmission line . This paper investigate the electrical performance of two types of insulator (porcelain and silicon rubber) used in service and subjected to pollution condition from Baiji Refinery and thermal power station of Baiji for more than(10) years .The test data of flashover voltage measurements, surface resistance measurements and the insulators hydrophobicity are evaluated. The test result show that the silicon rubber insulator has a better performance compare with porcelain insulator.
