Title:

PD PERFORMANCE OF UHV-DC TEST EQUIPMENT

 

Abstracts

The demand for reliable, economical and environmentally friendly energy is steadily increasing. This requires the transportation of energy over long distances at acceptable cost and losses. Recent improvements in the industry have allowed higher DC transmission levels at reduced costs and consequently the importance and total number of DC transmission have grown. Although voltage levels have been pushed as high as 800 kV, discussion is ongoing for even higher voltage levels. For research and production it is mandatory to have appropriate test equipment. Although DC test generators have been built since decades, the demand for low PD test systems and laboratories has increased lately. The industry standard for PD testing is the IEC 60270 ed. 3.0. The intention of the paper is to start the discussion in the HV community on these topics. The better understanding of PD behaviour for DC equipment will help to build more reliable equipment necessary for the reliable energy demand of the future.
