Abstract
A direct current breaker for a high voltage direct current application includes: two high voltage electron tubes arranged in an anti-parallel connection, and a control circuit for receiving, from a control system, infrared pulses including control information, the control circuit further including a device configured to convert the infrared pulses into electrical control signals, for controlling a switching status of the direct current breaker. An electrical power system includes such direct current breaker.
