ABSTRACT:
A device for detecting and locating arcs in a set of wires is discussed. The device comprises a probe for discharging controlled current to an exposed portion of a wire in the set of wires. The probe includes a handleable enclosure and an elongated structure which projects from the enclosure for conducting a gas and for enclosing a needle that has a tip. A suitable gas includes gases that have low electron attachment, such as helium. The device further comprises a control unit for communicating control signals as well as the gas to the probe. The control unit includes a controller, a valve being controllable by the controller and being capable of regulating the flow of the gas, and a high-voltage generator being controllable by the controller to generate a high-voltage signal, which can be communicated to the probe by the control unit.
