FIELD STUDIES OF THE TECHNOLOGY FOR ASSESSING THE CONDITION OF LINEAR INSULATION IN PJSC «ROSSETI MOSCOW REGION»

The article presents the results of testing the technology for assessing the state of linear insulation based on monitoring the leakage current parameters in a string of insulators. The technology allows for a quantitative assessment of the probability of insulator string overlap and power loss in them. A description of the hardware and software complex implementing the technology is given, which ensures the removal of leakage current oscillograms in three phases with a discreteness of 1 μs and meteorological parameters at the point of leakage current measurements. The dependences of the leakage current on external factors, as well as the degree of moistening of insulator strings under operating conditions, are revealed.
