A system (10) includes a sensor housing (12) having a base portion (14), a lidportion(16), and a joining portion (18). The joining portion (18) is configured to bewrappedaround at least a portion of an electrical wire (28). The lid portion (16)includes one end(20) detachably coupled to a first end (22) of the base portion (14) andanother end (24)coupled to a second end (26) of the base portion (14) via the joining portion(18). Aflexible coil sensor (40) is disposed in the sensor housing (12); bondedsubstantiallyalong the base portion (14) and the joining portion (18) and configured togenerate asignal representative of a fault in the electrical wire (28). A processingdevice (50) isdisposed in the sensor housing (12) and configured to detect and locate afault in theelectrical wire (28) in response to the signal representative of the fault inthe electricalwire (28) generated by the flexible coil sensor (40).
