Abstract
A fault sensing electrical wire ( ) utilizes one or more sensor strips ( ) which provide an impedance change when the wire is subject to an overtemperature condition or mechanical damage of the wire. A control unit ( ) measures the impedance of the sensor strips of the fault sensing wire and provides a control signal ( ) to initiate an alarm or protective action based on the severity of the condition. The control unit ( ) may monitor a number of fault sensing wires simultaneously or in sequence. The apparatus may be used to sense an electrical arc occurring in the insulation of the wire.
