SUMMARY
The discussion centers on the application of a 380V, 3-phase core type transformer used as an AC line choke in a Variable Frequency Drive (VFD). It confirms that connecting the R phase of the supply to any winding is permissible, provided the windings are consistent and not swapped end for end. Maintaining balanced phase currents is crucial to ensure a sum zero magnetic field in the shared core, which is essential for optimal transformer performance.
