HV insulated hot stick electric potential and field simulation

The high voltage insulated hot stick constantly used in live line maintenance of high voltage lines by the operator/personnel. The hot stick electrical requirement shall be withstanding the operating voltage, less leakage current, surface shall be free from contamination (dust& moisture) to avoid conductive. The simulation provides insight on the surface of the hot stick about the electric potential & field is distributed when the surface is dry & clean and when the surface is contaminated.
