Analysis of impedances by frequency responses and induced voltages on overhead power lines

Abstract

Line impedances were measured for frequencies from 1 to 500KHz. The high resistive-impedance distorted the propagation wave, and the distortion generated sine wave oscillation. The sine waves were superposed on transient voltages of the propagation wave on a multi-conductor system. The voltage waves by the proposed method in the paper showed a good agreement with the measured results.
