Abstract

The quality of winding wires unambiguously determines the operability and reliability of electrical equipment. Deterioration of wire properties leads to equipment failure and thereby causes significant material damage associated both with repair of the equipment itself and with downtime of the technical systems in which it is used. Therefore, continuous quality control of winding wires is required at all stages of their life cycle: during manufacturing, installation, operation, and repair. For this purpose, new methods of rapid nondestructive testing of winding wire defects and devices for their implementation are proposed. These methods are based on the capacitive technique for monitoring the parameters of insulated wires and make it possible to diagnose both structural elements of the wires—the current-carrying conductors and the insulation—as well as to perform rapid rejection of defective wires without the need to calculate the parameters of their defects. During operation of the diagnostic devices, a quasi-resonant mode is ensured in which the output signal reaches its maximum possible value. This increases the efficiency of winding wire quality control. The proposed systems make it possible to diagnose not only electrical wires but also other types of cable products, as well as long metallic products with a small circular cross-section, including those having an external coating of insulating materials, for example, metal-polymer ropes, wire, rods, and similar products.
