  • Arrester Earthing Resistance.pdf | Electrical Impedance

    The arrester will clamp the voltage across the plant to 64kV (i.e. 6.4 x 10) which is within its rating. The BIL of the insulators for 11kV systems is 95kV and for 33kV insulation is 170kV. The voltage rise of the phase conductor above ground due to the lightning strike is therefore approximately 481kV (i.e. 225 + 10 x 6.4 + 30 x 6.4
