Surge attenuation in cable systems

Abstract

Details an equivalent circuit model used to stimulate voltage surge attenuation within concentric cylindrical transmission systems. The model is frequency independent and accommodates the linear parameters of the current return path. To illustrate the validity of the approach, calculates the theoretical current distribution within an insulated cable and compares it with results obtained using a finite element analysis package. Finds that there is a good correlation between the two methods. Concludes that the model is simple to implement, has short computational times and can be readily adapted into any transient analysis program.
