Abstract

A high voltage valve arrangement includes a high voltage valve unit; an external electric shield structure arranged at least partially around the high voltage modular valve unit and a grounding system. The grounding system includes a grounding system configured to be remotely extended from a retracted position to an extended position, whereby the extendable grounding device establishes electric connection with the external shield structure when it is extended from the retracted position.
