Abstract:

 

Room-temperature vulcanizing  RTV  silicone rubber is used as a high-voltage insulator coating to enhance  the pollution performance of conventional insulators, and the electrical performance of RTV coating depends on the  several parameters. The present study shows the effects of the thickness on the leakage current, erosion, and hydrophobic  performance of high-voltage insulator coating. Several different thicknesses of RTV silicone rubber were taken into  consideration on porcelain substrates. Erosion and leakage current performances of the samples were evaluated by using  inclined-plane tests  IPTs  based on the IEC 60587 standard. Eroded masses and fundamental and harmonic components  of the leakage currents were investigated with respect to coating thicknesses. On the other hand, hydrophobic features  of the samples were evaluated by using dynamic drop tests  DDTs  with regard to CIGRE TB442 documentation. Time  to loss of hydrophobicity and the level of the leakage currents were investigated in DDTs considering the thicknesses.
