The charge transient which usually is of higher amplitude and lower frequency than the discharge transient is most suitable for fault location. This paper discusses a method for estimating a single phase to ground fault location in radially operated unearthed distribution network. The proposed method is based on correlation of undamped charge transient frequency with the fault distance. The undamped complex frequency is defined from the development of single phase to ground fault bus impedance matrix of the circuit network in complex frequency domain. The accuracy of the method was tested using a simulation model and the network example with overhead lines. The analysis was performed using the EMTP-ATP software. 2013-01-09T01:39:08Z 2013-01-09T01:39:08Z 2012 Article International Review on Modelling and Simulations, vol. 5 (4), 2012, pages 1765-1772 1974-9821 http://www.praiseworthyprize.it/public/SUBSCRIBERS/IREMOS.html http://hdl.handle.net/123456789/22908 en Praise Worthy Prize S.r.l.
