Abstract: The use of PSPICE program in HV engineering is shown. The calculation of voltage distribution along strings with standard cap and pin insulators, semi-conductive insulators and with both insulator types were performed. For calculation purpose a very known formula was used with constant stray capacitances. For PSPICE simulations the stray capacitances according to formulae proposed by Naito wee taken. Voltage measurement with a small air gap 10 mm sphere diameter were also carried out. The lightning and switching impulse flashover voltages were measured for both polarities.
