4.18 Fault Locator
Output of the fault distance
Trigger
Reactance per unit length setting (secon-
dary)
For the remaining parameters refer to the Power System Data 2.
When configuring mixed lines, the reactance per unit length value must be set for each line section (A1 to
A3).
Measurement tolerance as per VDE 0435, Part 303 for
sinusoidal measured quantities
1) Homogeneous lines or correctly configured line sections are assumed when the fault distance is given in km,
miles or %!
