This work presents an accurate and efficient 3D calculation of electro-quasistatic fields of HV devices. Application of bicubic splines for interpolation functions ensures smooth approximation of surface sources, leading to high accuracy of computations. The computation is based on integral equations approach. Accuracy of proposed approach is tested with FEM and compared with measurements of electric fields inside power facility.
