<p>A disc wound winding formed of a plurality of spirally wound, disc coil sections and having series capacitance increasing electrostatic shields in less than all of said sections, incorporates partial-turn electrostatic shields in disc coil sections adjacent that portion of said winding not having electrostatic shields. With this arrangement, a substantial reduction in the change in series capacitance between the shielded and unshielded portions of a disc wound winding is effected which minimizes unsatisfactory impulse voltage build-up at the beginning of the unshielded portion of said winding.</p> |
