Electrical and thermal analysis on optical ground wire cables in short-circuit regime by coupled equations
چکیده انگلیسی


• Was investigated the electrical and thermal analysis on optical ground wire cables.
• The study is carried out by coupled equations, i.e., electrical and thermal effects are analyzed simultaneously to increase the accuracy of calculations.
• Was proposed two modified OPGW.

In this paper, electrical and thermal analysis of optical ground wire cables in short-circuit regime is presented. The study is carried out by coupled equations, i.e., electrical and thermal effects are analyzed simultaneously. The electrical analysis is based on the electromagnetic field theory where the skin and proximity effects are taken into account. As for the thermal analysis, the principles of heat transfer by conduction and thermal equilibrium are used. The analysis is made for three types of cables. One of them is an existing cable and the two proposed cables are modifications of the existing one. The current density and temperature distribution in the cross-sections of these cables are presented and analyzed.
