| description | Silicone rubber provides an alternative to porcelain and glass regarding to
high voltage (HV) insulators and it has been widely used by power utilities since
1980's owing to their superior contaminant performances. Failure of outdoor high
voltage (HV) insulator often involves the solid air interface insulation. As result,
knowledge of the field distribution around high voltage (HV) insulators is very
important to determine the electric field stress occurring on the insulator surface,
particularly on the air side of the interface. Thus, concerning to this matter, this
project would analyze the electric field distribution of energized silicone rubber high
voltage (HV) insulator. For comparative purposes, the analysis is based on two
conditions, which are silicon rubber insulators with clean surfaces and silicon rubber
insulators with contamination layer taking place over its surfaces. In addition, the
effect of water droplets on the insulator surface is also included. The electric field
distribution computation is accomplished using SLIM software that performs two
dimensions finite element method. The finding from this project shows that pollution
layer distort the voltage distribution along the insulator surface while different
pollution layer material and variation in zone of incidence would contribute different
profile of electric field. Existence of water droplets would create field enhancement
at the interface of the water droplet, air and silicon rubber material. Also, the
intensification field created by water droplet is depending on the droplets size,
number of droplets and the proximity of water droplets to each other. |
