Abstract
An improved method for fault location on transmission lines using the maximum likelihood estimate of the arrival times of reflected travelling waves is presented. The method is compared with previously proposed correlation based methods using results determined by ATP. The effectiveness of the new method for small fault angles and close in faults has been detailed
