Effects of Creepage distance on Leakage Current of 220kV Long Rod Insulators at Different Severity Level of Salt Contamination
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 10
Abstract
In this paper, effects of creepage distance are examined of 220kv composite log rod insulator during different densities of salt contamination. Insulator is one of the most vital elements of Power transmission system at high voltage. The performance of high voltage insulator is strongly affected by environmental pollution in coastal regions. Long Rod insulator is widely used for good performance in pollution regions. The performance of polluted insulator mainly depends on the conductivity of the polluted surface layer or on the equivalent salt deposition density(ESDD). In this paper Leakage current is evaluated at different ESDD level of salt pollution on 220kV Long Rod insulator of different creepage length. The paper deals with three type of creeapage distance of composite long rod insulator. Model of insulator is obtained by MATLAB and results are carried out using simulink. The leakage current of all three type of composite long rod insulator with different creeapage distance is represented and discussed at different severity level.
