Abstract :
Description of a new type of operating mechanism for circuit-breakers having a rated voltage of 72.5 kV and above. It uses one moving part and is fully electronic. The energy powering the drive is buffered in a capacitor bank. The use of electronics allows for easy monitoring without the need for additional sensors
