What is HVDC Transmission Systems? HVDC (High Voltage Direct Current) transmission systems are a technology for transmitting electrical power over long distances. Unlike traditional HVAC (High Voltage Alternating Current) transmission, which oscillates between positive and negative cycles, HVDC transmits electric power in a unidirectional manner. Here are key features and components of HVDC transmission systems: …
