The use of compressed gas-insulated equipment in the high voltage transmission network has steadily increased over the recent years. Substations utilizing compressed gas insulation can be placed and used to bring power into urban areas at the full transmission line voltage. Compressed gas-insulated cables have found an increasingly important role in this development for feeders and interconnections to substations. The HVDC alternative has an approximate 2 : 1 advantage over an ac system for power delivery in a given corridor. Interconnection of ac systems with a HVDC link allows the ac systems to operate asynchronously and reduces the short circuit currents both of which allow increased power transmission into urban areas without overstressing the existing ac equipment. A HVDC transmission system also allows operation at reduced voltage, and temporarily with one conductor out-of-service, this gives increased reliability to the power system.
