摘要： A stationary induction apparatus superior in insulating ability against a surge voltage includes a coil piece on a line end side surrounded by one electrostatic shield insulating layer. The coil piece and electrostatic shield insulating layer, together with another coil piece, are surrounded by another electrostatic shield insulating layer, thus forming a successively nested configuration. Each of the electrostatic shield insulating layers includes an electrical insulating layer of pressboard and first and second conductive layers respectively located on inner and outer surface sides of the electrical insulating layer, The capacitance of each of the electrostatic shield insulating layers is adjusted to control an electrical potential distribution upon application of a surge voltage.

摘要： A transformer winding characterized by a plurality of electrically connected disc or pancake coils disposed around a core leg in which the inner and outer edges of adjacent coil pairs are radially offset, enabling the insulative members which surround the edges of each such coil pair to be curved and thus more closely conform to the equipotential planes of the dielectric field.
