ELECTRICAL TRANSFORMER HAVING CORONA SHIELDING MEANS

摘要

An electrical transformer of the shell type characterized by a phase winding disposed in inductive relation with a magnetic core with a low voltage coil around the core leg and a high voltage coil wound concentrically about the low voltage coil. Corona shielding is disposed between the coils as well as around the outer high voltage coil. The outer coil employs special winding whereby the combination of the winding and shielding provides better controlled voltage stresses and directly reduces internal failures.
