Siemens presents a gas- insulated switchgear for DC ... German company Siemens has introduced the first compact gas- insulated switchgear (GIS) for high- voltage direct current applications. These armored switchgears require 95% less space compared to air isolated ones. When used in offshore platforms, their size can be reduced by up to 10%.
History of High Voltage Direct Current Transmission (HVDC)· PDF fileThe heart of a HVDC Transmission System is truly the electronic power converter valves. These valves are built around the thyristor device and they convert AC into DC at the Rectifier station and DC into AC at the Inverter station. Originally, the thyristors were triggered with an electrical current pulse,
