Zolotaryov V. The devices for electrical testing and parameter monitoring of cables and wires with insulation of cross-linked polyethylene

Investigation object - process of interaction of stationary electric field with a dielectric in the form of the sewed polyethylene the response from which bears the information on a condition of isolation of cables and wires. Target of investigation: working out of the devices of electric tests protected from electromagnetic hindrances and control of parameters of cables and wires with isolation from the sewed polyethylene. Investigation methods and equipment: aspects of dissertational work are based on analytical methods of mathematical physics and the theory of linear electric circles, and also on a numerical method of linear algebra (a method of finite elements). Theoretical and practical results: the range of change of controllable parameter - a tangent of angle of dielectric losses in the multilayered sewed polyethylene isolation is theoretically defined; devices of tests and control of parameters of the sewed isolation of cables and wires are developed. New: New devices of electric tests and control of parameters of cables and wires are developed. Degree of introduction: the PJSC Yuzhcable Works the new devices of tests protected from hindrances and control of parameters of cables to 110 kV and to 330 kV on test pressure to 500 kV. Sphere of use is introduced in industrial production: results of work are used in system of improvement of professional skill of technical experts in the field of electric power industry and at a construction and operation air of transmission lines on pressure to 1 kV.
