1. Series-capacitor compensation equipment comprising:

  • (a) a series-capacitor bank for connection in series with a power line,(b) an overvoltage protection circuit for the series-capacitor bank for connection in series with said power line and in parallel with said series-capacitor bank, the overvoltage protection circuit comprising the series combination of a surge arrester and bus structure, the surge arrester comprising an insulating housing and varistor elements within said housing, said bus structure being located externally of said housing and connected in series with said varistor elements, and in which;

    (c) said bus structure comprises stainless-steel bus conductor having a resistance that is sufficiently high to effectively limit the energy duty on the surge arrester during discharge of said series-capacitor bank through said overvoltage protection circuit in the event of a failure of a varistor element during surge-arrester operation.
