It is based on a literature review and discussions with experts from manufacturers and utilities. It concludes that 800 kV is a clearly feasible voltage step with existing knowledge, 1000 kV is practicable with further research effort, but that 1200 kV is unlikely to be economically feasible without a technological breakthrough. The principal problems identified are: l) The behaviour of external insulation in bad weather, especially in polluted situations 2) Transformer insulation Controlled gas insulation 3) Surge arrester limitations Methods of controlling overvoltages.
