- Murray_loop_bridge abstract "Murray loop bridge is a bridge circuit used for locating faults in underground or underwater cables. It has been used for more than 100 years. One end of the faulted cable is connected through a pair of resistors to the voltage source. Also a null detector is connected. The other end of the cable is shorted. The bridge is brought to balance by changing the values of RB1 and RB2, which is achieved when:which is equivalent to:The value of resistance Rx is proportional the length Lx, thus the location of the fault can be calculated:where L is the total length of the cable under test - a value proportional to Rg.The method assumes a single fault exists, of low resistance compared with the undamaged cable insulation resistance, and that the cable conductors have uniform resistance per unit length.".
