Zinc-oxide arresters without series gaps have been used for HVDC systems. The voltage wave shapes applied to HVDC arresters are not a simple sinusoidal shape, so that the leakage current contains high frequency components. The power dissipation characteristics of a thyristor valve arrester were measured using a 1/25 prorated arrester section with a 5kV/500kW thyristor bridge. High frequency power dissipation characteristics of zinc-oxide elements were measured and it was shown that the high frequency power dissipation of the thyristor valve arrester was larger than that of an AC system arrester. Consideration of the equivalent continuous operating voltage for the performance test of an HVDC arrester are presented.
