KES 1215 : MESUREMENT AND INSTRUMENTATION Wheatstone bridge Application: (Varley Loop Test) A Varley loop test is an application for Wheatstone bridge. The test is one of the most accurate tests of locating faults in sheathed cables or finding a short circuit in multi-core cables. It is a modification of the Murray loop test. It consists of two fixed ratio arms R1 and R2 and a rheostat R3 in the third...
