Abstract :
Electrical joints can be weak points in the electric supply system. Based on theoretical and experimental investigation, a mathematical model is presented which describes the resistance characteristic of joints depending on parameters such as conductor material, load, design, assembly quality and its surroundings. Furthermore, using the example of busbar joints, a possibility of how limiting values for the joint resistance can be determine using a mathematical model.
