摘要: This invention concerns a device and method for inspecting aluminum cables with steel core (ASCRs), installed in energized electrical energy lines, which use the ECT (Eddy Current Testing) technique evaluating remaining thickness of zinc layer covers wires inspected, where readings tension detection solenoid current excitation are taken as conductor reaches zero, parameters corrected average temperature during inspection signal from is filtered through hybrid circuit designed to increase sensitivity measurement.
