A lossless transmission line with $0.2$ $\text{pu}$ reactance per phase uniformly distributed

along the length of the line, connecting a generator bus to a load bus, is protected

up to $80$% of its length by a distance relay placed at the generator bus. The 

generator terminal voltage is $1$ $\text{pu}$. There is no generation at the load bus. The

threshold $\text{pu}$ current for operation of the distance relay for a solid three phase-to-

ground fault on the transmission line is closest to:

  1. $1.00$
  2. $3.61$
  3. $5.00$
  4. $6.25$
