The space charge accumulation and dissipation characteristics of the oil-paper insulation systems composed of different types of transformer oils were studied under the conditions of applying and removing different intensity of DC electric field. The results show that compared with paraffin-based transformer oil, the naphthenic transformer oils have higher naphthenic hydrocarbon content, more suitable aromatic hydrocarbon content, and higher charge transfer rate, and the oil-paper insulation systems composed by them has less charge accumulation and the charges dissipates more easily after applying and removing the high voltage DC electric field, which is beneficial to the dissipation of charge in oil-paper insulation for converter transformer.
