Abstract
Cast-resin type current transformers are widely used in power systems due to their good insulation, light weight and high reliability. Compared with the oil-immersed current transformer, the external electric field strength of the cast-resin current transformer is more complex and unevenly distributed. To improve this problem, this paper takes a kind of conical casting type current transformer as the object. Firstly, a geometrical model is established to simulate and analyze its external electric field distribution, then an improvement scheme is proposed, and finally the improvement scheme is optimized. The results of this study can provide a reference for the design of the transformer and the optimization of the local discharge.
