Abstract
Thermodynamic method for detecting degradation of insulation in diagnostics and forecasting resource cable systems
Incoming article date: 13.09.2017The problematic issues of the state of isolation of power cable systems (PCL) are considered on the basis of development and development of non-destructive testing methods. The main components that destroy the PCL isolation are established. An analytical method for evaluating the processes of cellulose oxidation with the definition of the most probable is proposed. The calculations of thermodynamic processes of cellulose oxidation are given. Using the proposed approach to studying the basic processes of insulation failure allows us to provide more detailed information on the prerequisites for the development of partial discharges (PD) in isolation and to determine the necessary measures to minimize the processes leading to the destruction of the insulation of power cables
