The Effect of Cable Aging on Surge Arresters Designed by Genetic Algorithm

Abstract

The degradation of communication cable insulators reduces the availability of the train control system and is caused by the degrading of data transmission line parameters. Due to extremely varying environmental conditions in the railway industry, the effect of data transmission line degradation on the critical parameters of the surge arrester that is used in wayside equipment is not known. The surge arrester module is very important in the railway industry, as it enables the protection of sensitive parts of wayside equipment, especially communication interfaces existing in wheel detectors, evaluators, signals, etc. These are critical to the safe and efficient management of railway infrastructure. The process of selecting a surge arrester component for a two-level voltage input to enable the examination of the degradation impact of a cable insulator used in rail signaling equipment on the performance of the surge arrester is presented in this paper based on the standards, as well as practical experience. To achieve this objective, an innovative design of the goal function that can be adapted to the new requirements of various industry sectors is proposed. The use of a two-stage solution verification is a unique feature of this method. The results indicate that the proper selection of the arrester components ensures the effect of degradation of the communication cable has an insignificant influence on the power dissipation of the surge exposures.
