The power frequency electric field in the HV substation has aroused more and more attention. In the paper, the power frequency electric field in 500kV substation is calculated using the boundary element method considering the influence of the switching equipment. According to the structural characteristics of the switching equipments, the indirect boundary integral equation of the suspension electrode...
