Abstract
The manufacturing process of the amorphous transformer core consists of winding, cutting, forming, annealing. Clamping of cores during this process are required for shape forming. Clamping of cores enhances the space factor, but degrades the magnetic properties and core loss characteristics of the cores. In this study, we investigated the optimal clamping pressure required in magnetic field annealing of 5 kVA amorphous transformer core.
