Experimental study for the lightning impulse V-t characteristics of the anti-pollution-type distribution insulator under dry and polluted conditions was carried out to establish insulation coordination throughout the power distribution system. This paper proposes an approximate formula having three independent variables and evaluates the parameters to calculate the V-t characteristics. Many experimental data fit with the proposed approximate formula for various conditions.
