“…When it detects a defect, the parameters are displayed ( Figure 7). The presented capability of the device CAP-10 extends the scope of its application and provides additional capabilities of spark testing in non-destructive testing in the cable industry [1,2]. no defect a defect is detected Test results for the sample free of defects and that with a detected defect.…”

“…For this purpose, specially prepared segments of the tested wire with different insulation materials and known values of the capacitance per unit length within the limit of CAP-10 measurement are used [2,4]. The actual values of the wire capacitance per unit length were determined in compliance with GOST 27893-88 "Communication Cables.…”

“…Therefore, the variation of the capacitance per unit length indicates change in the wire geometric dimensions or insulation electrical properties. The need to ensure the stability of the electrical and geometrical parameters of the entire length of the cable products requires continuous in-process control of these parameters [1][2][3][4][5]. A continuous capacitance control can solve this problem.…”

“…The wire capacitance depends on the characteristics of in-process insulation applying; therefore, the capacitance control is to be carried out during extrusion [1,2,[6][7][8]10]. The only possible embodiment of the measuring transducer in this case is the use of the tubular electrode [11] immersed in cooling water together with the test wire.…”

Abstract. The paper presents technical implementation of the electricalcapacitive method to perform in-process measurement of the capacitance per unit length of a single-core electric wire. The design of the electrocapacitive measuring transducer is proposed. The block diagram of the device CAP-10 developed to implement the proposed method is presented. The appearance of the device CAP-10 is showed, and its operating principle is described. It is shown that the change in water conductivity has a significant impact of the measurement result of the wire capacitance per unit length. The techniques to offset from the impact of water conductivity variation on measurement results are proposed. The technique of the device CAP-10 initial adjustment is proposed. It provides the desired function of the output signal transformation. The technique of the "operating" adjustment to correct measurement results through systematic measurement error elimination is offered.

Abstract. The paper presents a three-dimensional method of measuring diameter and ovality of cylindrical objects in diverging laser beam. Mathematical software method is developed. Virtual simulation of this method and experimental testing are made. The results can be used for design and manufacture of optical devices, which will be used for technological control of external diameter of cable, wire, trumpet and other products.
