Abstract
Polymeric insulation is widely used as the main insulation of power equipment and electronic devices. When DC voltage is applied on the polymer insulation, space charge may accumulate inside and cause electric field distortion. So, space charge accumulation is important for HVDC insulation materials. The origin of the space charge is considered to be from ionization and charge injection. The space charge accumulation is determined by the charge injection, transportation, extraction, trapping, and other factors. The charge injection rate at the electrode/insulation interface is a key factor that determines the charge accumulation inside insulation material.
期刊介绍：
The EI Magazine publishes articles written by authors from industry, research institutes and academia. The articles are more practical in content than the papers published in the Transactions. Usually three articles are published in each issue. The articles deal with dielectric materials, processes and new developments applied to industry products. Also the EI Magazine is used to promote upcoming conferences and solicits papers for the conferences. In addition, reports on past conferences are given in many issues. Book reviews and news items are included. An editorial is written by both the EIC and the President of DEIS in alternate issues. Advertising of insulation products appears in many issues.
