A new method for defectoscopy of electrically conductive cable elements is proposed, according to which, using the appropriate spin modulators, directional alternating electric fields are created, which simultaneously affect the controlled cable and the reference additional finite length of the cable segment without defects. Thus, wave processes of polarization of the spin magnetic moments of free electrons at the resonance frequency of this polarization are excited in the electrically conductive elements of the controlled and reference cables and the control and reference signals are recorded in the form of induction emf due to the indicated wave processes by means of corresponding induction sensors. The real and imaginary components of these signals are formed in real time and by the difference values between the material components and between the imaginary components of the reference and control signals, tolerance monitoring of the physical and technical state of the electrically conductive elements of the controlled cable is carried out according to the values of the normalized difference values. A device is proposed that implements the developed flaw detection method and allows for operational control of cable quality. The conducted experimental studies confirmed its high efficiency and reliability of control.


Electric cable, electrically conductive elements, non-destructive testing, spin modulator; induction sensor, polarization of the spin-magnetic moments of free electrons, resonant frequency, dielectric constant, specific conductivity, synchronous detectors of quadrature and in-phase components of the signal.
