AMPLIFICATION OF ELECTROMECHANICAL STRESSES BETWEEN CLOSELY PLACED WATER MICRO-INCURRENTS IN THE INSULATION OF HIGH-VOLTAGE CABLES UNDER THE INFLUENCE OF AN ALTERNATING ELECTRIC FIELD
For crosslinked polyethylene insulation of high-voltage and ultra-high-voltage cables, a mathematical model of its electromechanical degradation near water micro-inclusions has been developed based on a combination of electrostatic and mechanical analysis. The finite element method has been used to simulate the distrib...
