Creation of resonant energy-efficient installation for the certification tests of domestic cables with modern insulation on high and ultra-high voltages

Electric circuit diagrams and technical solutions, which improve technology formation of low-frequency ultrahigh voltages (up to 500 kV) for certified tests of power cables with modern po-lymeric insulation on voltages to 330 kV are developed.
Circuit diagrams and solutions are based on practical realization of a power series resonant contour with adjustable precision Q-factor (Q ≈ 40) in the test installation that provides formation of resonant test voltages with instability ≤ 1 %.

Development of scientific and technical means of non-destructive diagnostics of domestic superhigh-voltage cables of world level to improve their operational reliability and service life

Application of cables with nano-hardened cross-linked polyethylene (XLPE) insulation is a strategic way to improve the reliability and ecological compatibility of systems of power supplies in all countries. However, there is no normative base for the diagnosis of these cables in Ukraine. Besides there is no necessary diagnostic equipment, despite the fact that the plant "Pivdenkabel" (Kharkiv, Ukraine), the first in the CIS mastered their industrial production for voltages up to 330 kV.

Optimization of new technology for industrial production of cables with solid polymeric insulation for improvement of energetic networks of ultrahigh voltages.

The essence of development is to provide scientific and technical support of industrial production in Ukraine of world level EHV cables, which are not produced in CIS countries. The recommendations and technical solutions to optimization of new technology of cable production with solid polymer insulation for voltages up to 330 kV have been developed, in particular it has been developed new methods of optimization technology of insulation covering on the moving conductor and its nano-structural vulcanization in inclined type chamber. New methods are based on the development of:
