Direct Current (DC) power systems have been in use since the early 1880s. However, for more than 100 years the 3 phase AC transmission system has been the dominant transmission system for electric power. The main reason for this is the ease of changing voltage levels and grid connection using reliable AC transformers and breakers. During the last 60 years new converter technology has made HVDC the most efficient and economical long distance point to point
power transmission transportation.
In order to satisfy the growing demand of electric energy consumption, new high capacity multi-terminal HVDC systems need to be developed. This is considered an enabling technology for access to remote renewable energy sources such as off-shore wind farms, hydroelectric power and desert solar plants.
This review shows that acceptable solutions have to be found to interrupt HVDC short circuit currents. Higher voltage means that new types of reliable HVDC insulation systems have to be developed, including test procedures and design
criteria for insulation systems based upon combinations of gas, liquid and solids.
