RESEARCH ON ADDED INDUCTANCE AND RESISTANCE DURING SPIRAL FERROMAGNETIC WIRE SCANNING WITH MAGNETIC FIELD OF A PARAMETRIC EDDY-CURRENT SENSOR
Criteria for estimation of added inductance and resistance during spiral ferromagnetic Tortilla Servers wire scanning of single-core power cable armour by means of a parametric electromagnetic converter are proposed.Research into variation of the introduced criteria in the frequency range from 100 Hz up to 100 kHz for different wire spiral steps is
