This paper deals with the interruption scheme designed using Vacuum Circuit Breaker (VCB) based on zero crossing characteristics, implemented electromechanically for High Voltage Direct Current (HVDC) system. The operation is carried out using Mechanical scheme as it has minimum energy loss in comparison to Solid-State and Hybrid schemes. The Mechanical scheme consists of series connection of multiple...
DC neutral breakers are used to reconfigure HVDC transmission systems. One example is the Metallic Return Transfer Breaker (MRTB) that commutates the current from the ground to an overhead line or cable reducing time duration with current flowing in the ground path. An MRTB consists of a passive LC-circuit in parallel with an AC breaker that triggers a resonance by its arc voltage characteristics,...
