Abstract: “The cabtyre cables are widely used in power distribution systems. It is necessary to have an accurate cable models to predict switching or lightning surges. Transient characteristics on the cabtyre cable are measured. The cabtyre cable frequency characteristic of characteristic impedance and propagation constant are studied and discussed for aerial mode. It is found for the aerial mode-2 cable characteristic impedance can be represented by RL series circuit. The attenuation increases as the frequency increases. This study supports to develop a generalized frequency dependent cabtyre cable model.”
