Abstract :
Understanding the propagation of transient pulses in high voltage power cables is valuable in several applications such as surge protection schemes for underground distribution (UD) cable systems (Dugan and Sponsler 1978). It has been shown by Stone and Boggs (1982) that a pulse suffers frequency-dependent attenuation in a plastic insulated UD cable because of the semiconducting layers present in it. This paper describes a new nondestructive technique for determining the attenuation in such a cable. The method is based on measuring the impulse response of the cable in the time-domain and computing the attenuation as a function of frequency via Fourier transform
