ABSTRACT:
Capacitively coupled, transient response improving, series capacitance compensating electrostatic shields in a disc-wound winding progress inwardly from the outer portion of said winding in a tapered configuration or inwardly and outwardly in a conical-taper configuration, as the winding progresses from a high potential end. With this arrangement a substantial reduction in the change in series capacitance is effected between the compensated and uncompensated portion of said winding which minimizes unsatisfactory voltage transient build-up at the beginning of the uncompensated or lower series capacitance portion of said winding.
