Abstract :
The paper presents results of digital computer calculations of the sheath overvoltages and the energies absorbed by sheath-protecting surge arresters in a crossbonded cable system. Especially, the energy loading of the arresters during energisation and discharge of an underground cable-overhead line configuration is considered. An analysis of the natural wave propagation characteristics of the cable system is given. Based upon this analysis a frequency-independent wave propagation of all modes has been adopted as a basis of the calculation method. The requirements concerning the choice of the arrester are discussed.
