Electric power system

Question: 02 Murray loop test is performed on a faulty cable o performed on a faulty cable of 300 meters long. At balanced, the sum of resistances connected to faulty core ces connected to faulty core and sound cable is 6022. The fault is in the middle of the cable. Find the resistances con e cable. Find the resistances connected to faulty and sound cable? (ET) (5 Points)

Answer 1

Murray loop. test for locating rullian. be figured as below . 1 Test R - For sound cable (R) end m 3oomtr Faulty cable low giesistance connection & Ecorth - fault . Earth patah Güven faulty cable = 300 ml. or the sum of gresistances connected to feully core cop and sound coble (R) = 60. 1. so, R + Rs = 6or > 0 have . Rg=RE so for both take one variable on so, R=R=on. so, by substituting pl.in condition 1 here we

- we have 2 = 602 =>. RR autor 0 - - = 60 = 60 30=60x2 = 30= 120 9 = 120 = 40 9=you e So, we have. guesistance connected faulty and sound cable = 9 to we have r= your en 2 = 40 = door
