This study has been carried out using ATP (Alternative transient programme) simulator. Comparison has been made between the power frequency voltage and withstand switching voltage and that of withstand lightning voltage. Study has also been carried out to find the effect switching without and with pre-insertion resistor. Voltage wave forms have been shown. Some numerical calculation have been done. A flow chart has been drawn to show the methods of finding system parameters. Results have been tabulated and discussed.
