This paper presents tower surge response calculations on an actual transmission tower including ground wires and phase wires. A frequency-domain partial element equivalent circuit (PEEC) method is applied as a simulation tool. Insulator voltages calculated by the voltage difference of crossarms and phase wires are compared with experimental results collected from the literature. In addition, a transmission line (TL) model is adopted with the PEEC method to increase efficiency for transient surge calculation. The results calculated by the PEEC method with and without the TL model agree well with the experimental results not only for amplitudes but also for waveshapes.
