A novel time domain analytical method for predicting EM (electromagnetic) field transients resulting from power line switching operations is presented in this paper. This method which is directly derived from EM field theory of a power transmission line, allows the field transients to be accurately and efficiently calculated. It can be proved that conventional numerical methods for computing transmission line transient EM fields are in fact degenerative approximate models of this analytical method.
