Never try to replicate conditions given in the paper, in practice. Though the uploaded data and conditions are from real practical scenarios only,this dataset and paper is on short circuit study which means high voltages, electrical shock, fire hazard , personal injury,explosion,property damage etc. If the faults are copied,the first thing that happens is lifetime personal injury as the fault is in microseconds or nanoseconds & the author is not responsible for any mishappening.
