Abstract

Improvements in three-phase transformers, whose cores that carry the high-voltage and low-voltage coaxial coils are arranged at 120º from each other in the same plane, the average electrical height of the coaxial coils being taken along the axis of the coil, and providing the transformer a power, characterized in that the average electrical height in millimeters is between thirty times and sixty times the fifth root of the transformer's power in kilovolt-amperes.
