The Electromagnetic Force between Two Finite Parallel Rectangular Conductors

Increasing the loads of power station, electric furnace, electric welder, the counterplan for short-circuit forces on busses and bus supports is necessary. Rectangular conductors are used freqently in above mentioned apparatus, for they are electrical and mechanical advantageous. There are many investigations on the electromagnetic force between two parallel busses. For infinite length, Dwight and Higgins research and for finite length Ramamoorty et al. do. Using their formulas, force per unit length of the bus may be calculated. Nevertheless the distribution of forces cannot be obtained by them. With a view of this point, the electromagnetic forces are analyzed and a formula for the distribution of forces is obtained. For the numerical example, the distribution of force is shown.
