Furthermore, the development of a new protection device where it is implemented is presented. The performance of the proposed method has been evaluated in a 20 kV distribution network modelled in PSCAD/EMTDC. Results from simulations are presented, varying ground resistivity, fault resistance, fault type and the location of the fault; furthermore, harmonic distortion has been considered in the distribution network model. %U https://sciarena.com/article/fault-location-method-based-on-travelling-wave-theory-case-study-in-a-20-kv-distribution-network
