ROGOWSKI COIL EVALUATION PERFORMANCE WITH DIFFERENT FAULT CONDITIONS IN MEDIUM VOLTAGE DISTRIBUTION NETWORKS

In this paper, Electromagnetic Transient Program-Alternative Transient Program (EMTP-ATP) test bench of 20 kV network is developed considering high frequency models of Rogowski coil and the distribution network. The bench test is used to evaluate the Rogowski performance with different fault scenarios such as different fault types, different fault resistances and inception angles. Furthermore, the tree leaning fault and arcing fault with characteristics of intermittent faults are considered in the study. Results show the possibility of using Rogowski coil for locating faults in
