Mathematical model of electromagnetic field with skin-effect in closed electrical contacts (2017)
Journal Article

The mathematical model describing electromagnetic field in closed electrical contacts is elaborated. It takes into account a non-uniformity of the current density on the contact spot which can be explained by three factors: 1) physical phenomena of t...
