One transmission line has an impedance including a line of 6 + j8 ohms.
When each Fault occurs, there is very little arc resistance so it can be ignored.
If the impedance relay is set to look like Working in a circle, a radius of 8 ohms with a center point at the origin.
The relay can prevent the Fault from thinking about how many percent of the total transmission line length.
A. 70%
B. 75%
C. 80%
D. 90%
