Increase of Accuracy of the Fault Location Methods for Overhead Electrical Power Lines

Table 2

Influence of the different methods of derivative calculation and different distances to the fault on the first-moment fault location error.

Calculation method	Method 1	Method 2	Method 3	Method 4
(%) ( = 100 km)	0.042	32.21	3.02	−1.21
(%) ( = 10 km)	0.667	51.39	15.44	4.07
