A power system comprises of double circuit transmission systems, two generators (one each at the extremes of the transmission system) through two separate busbars. The generators are rated 120 MVA, 15kV each with reactance j0.1pu. One circuit of the transmission system comprises of two buses in series connection of reactance j0.1Ω each. The other circuit of the transmission system also comprisesof two buses in series connection of reactance j0.1Ω each. A fault occurs at thejunction between the buses on one of the circuits. Draw a single line diagram to represent the power system indicating the fault. find the following i) total reactance ii) pu fault current iii) actual fault current iv) pu fault VA v) actual fault MVA PLEASE ANSWER THE QUESTIONS ACCORDILY. THANK YOU.
