To date, the skin effect has not been considered in the analysis of network fault response and the design of protection systems for DC networks. However, the naturally high resonant frequencies of some modern marine and aerospace electrical networks under electrical fault conditions suggest that skin effect should be investigated more closely. The studies reported in this paper compare the system fault response for both a conventional circuit model and a model incorporating the skin effect. The results show a noticeable difference, demonstrating that in some cases the skin effect should be considered for studies of this nature. The paper builds upon these findings by investigating the impact on protection system operation, making recommendations for associated modelling and simulation practices.
