Abstract

This application describes methods and apparatus for the safety and protection of capacitor units suitable for medium and high voltage applications, for instance within switching modules () of a voltage source converter as may be used for HVDC or FACTs. The capacitor unit () has a housing () within which is a capacitor comprising a plastic film dielectric material, for instance a winding () of first and second plastic films () with metal coatings (). A pressure sensor () is configured to detect if the pressure in the housing exceeds a first pressure level and a pressure relief valve () is configured to vent gas from the housing if the pressure in the housing exceeds a second pressure level which is higher than the first pressure level.
