摘要:
An apparatus and method for communication between low potential level and a valve of a high voltage converter station located on high voltage potential level is provided. The apparatus comprises means adapted to send serial messages on light conductors between a valve control unit and a first control unit for controlling semiconductor components of the valve of turn-on type on high voltage potential level in periods of time when the respective light conductor is free from signals associated with a change in the conducting state of the semiconductor component, such as turn-on and/or indications signals.
