Abstract
The main purpose of this study is to analyze the magnetic forces developed in a transformer using aluminum strip conductor when subjected to a fault at its output terminals. This would be the most severe fault situation possible. Very closely related to this problem is the considered of current distribution and losses in this type of conductor. Whenever current-carrying conductors are located in magnetic fields, forces will be developed which tend to cause movement of the conductors. These forces usually are negligible under normal rated conditions but become most severe under extreme “Short-circuit” conditions. At the present time, this author does not know of the existence of any published information pertaining to the mathematical determination of these forces in transformers using this type of winding. In order to calculate these forces, the current distribution must be known. Whenever the current distribution is not uniform, the magnitude of the resistance or ohmic losses will be affected. A manufacturer furnished design information for a distribution transformer unit using aluminum strip conductor for the low-voltage winding and the conventional wire-wound coil for the high-voltage winding. It was then intended to compare the forces developed with the tensile strength of the specific aluminum material used in the drill.
