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,
The Top 25 Gas Insulated Substation (GIS) Companies concept of the gas insulated substation was introduced in 1920 when oil was used as the insulating medium in the system. A substation is considered as one of the vital element of power system infrastructure. Presently there are two types of substations primarily being used: Air Insulated Substation (AIS) and Gas Insulated Substation (GIS).Price Range: £3,499 - £6,999
