Power cables as one of main components of power networks, play an important role in electric power transmission between different zones. Because of probable incidence of water tree phenomena, air cavity and also humidity in electric insulators, increase in electric field happens locally and can lead to breakdown in insulator. The goal of This paper is determining humidity and air cavity effects in...
Power cables as one of main components of power networks, play an important role in electric power transmission between different zones. In cable insulation system, due to the presence of pollution such air voids, water voids, and also occurrence of water treeing phenomena, local field increase. As a resulting, enhancing electric field can cause local breakdown in cable insulation. The presence of...
In this article, we present our investigations on the radiation of the power-line communication (PLC) system. Power line communication or power line carrier is a technology for carrying data on a conductor usually dedicated to electric power transmission. At high frequency, the power lines, whose are dimensioned and adjusted for electrical energy transfer, not to carry high frequency (HF) data signal,...
