<p>A device for supervising different positions of a valve of a high voltage converter station located on high voltage potential level comprises member (18, 19) arranged on high voltage potential level and adapted to detect function parameters of the valve on high voltage potential level and send values detected thereby to first control units (3) for controlling the semiconductor components (4) of the valve. The first control units have means (20) for processing said detected values and the first control units are adapted to utilise light conductors (13) running back therefrom to a valve control unit (1) for sending data resulting from said processing to an arrangement (16) for supervising said valve located on low potential level.</p> |
