ABSTRACT:
Transformer cores are made electrically conductive during impulse voltage condition when a certain voltage is attained by a coating of semiconductor material applied to the edges or surface of the core laminations. Under ordinary operating conditions the semiconductor material provides a high resistance path to charges in the core. Upon the occurrence of a high voltage impulse, the semiconductor material rapidly equalizes the charges in the laminations and so avoids the danger of breakdown of the insulating coatings between individual laminations.
