Summary :

In this presentation the authors consider in detail the problems relating to parameters like contact normal force, the effective contact areas and the surface plating, which have significant influence onto the surge current strength of electrical power contacts. Obtaining the behaviour of machine turned pin and socket contacts with different pin diameters the parameters of the active contact area radius, the constriction resistance and the constriction temperature are calculated by using FEM for elastic/plastic surface deformation. With the knowledge of the constriction radius the temperature curve of the contact area was determined by coupled electrical/thermal FE calculation. Laboratory tests were carried out in order to verify the FE-calculation.
