High-voltage direct current - Wikipedia high-voltage, direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for the bulk transmission of electrical power, in contrast with the more common alternating current (AC) systems.. Most HVDC links use voltages between 100 kV and 800 kV. A 1,100 kV link in China was completed in 2019 over a …
Gas-Insulated Substations - GIS Dielectric Gas. A gas-insulated substation (GIS) uses a superior dielectric gas, SF6, at moderate pressure for phase-tophase and phase-to-ground insulation.The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in SF6 gas inside grounded metal enclosures.
Converter Stations for 800 kV HVDC - ABB· PDF fileB. Converter configuration/station layout The configuration of the HVDC main circuit has been carefully analyzed,. For example, the pole configuration, with two converter groups in series halves the power loss upon loss of a converter group, and with adequate switchgear, ensures that a group outage will not result in a pole outage.
