Electrica: HVDC Transmission transmission now became practical when long distances were to be covered or where cables were required. The increase in need for electricity after the Second World War stimulated research, particularly in Sweden and in Russia. In 1950, a 116 km experimental transmission line was commissioned from Moscow to Kasira at 200 kV. The first commercial HVDC line built in 1954 was a 98 km ...
Glossary of Medium Voltage Switchgear Terms· GIS equipment is a type of metal-clad switchgear construction, where all the switchgear power components are located inside of a sealed metal envelope filled with (usually) SF6 gas. GIS equipment is often supplied into high voltage applications, but there are now offerings at medium voltage.
SF6 Gas Insulated Switchgear(GIS) Manufacturers and ... SF6 load switch is sealed in a closed device filled with SF6 gas. Check the SF6 barometer to ensure that the air pressure is between 0.4 and 0.5Mpa. The pressure gauge will change with the change of external temperature. If the degree exceeds the green range, it should be stopped immediately and notify the company.
