Electrical-Thermal-Mechanical Analysis of Cable Connection with Screw-Connected Terminal Strips Using Finite Element Method

Electric energy passes through many stages from production to usage, and electrical connections take place at these stages. Electrical are quite important for system safety quality. In this study, current-temperature relationship in the cable was investigated joints made with screw connection terminals, depending on torque applied screw. numerical solution of problem, Comsol Multiphysics program based Finite Element Method used first, screw-conductor interface torque, then electrical-thermal analysis performed geometry. Experimental studies were carried out demonstrate accuracy digital model, conductors terminals household installations taken into account studies. Amount deformation its effect current carrying capacity having investigated. appropriate value is 0.4 Nm, maximum temperature 45 oC contact surface. Also, it has been shown that optimum be copper conductor joint 1.5 mm2 cross section area Nm.
