Electrostatic shielding of disc windings
Abstract:
An electrostatic shielding arrangement for improving the initial distribution of voltage which in turn reduces the insulation stresses on disc-wound coils resulting from the application of impulse or steep wave-front voltages to such coils. Floating electrostatic shields are placed near or internal of the innermost or the innermost and outermost turns only of a disc coil section. Shields are connected together in pairs, with no more than one shield connection being made between adjacent coil sections.read more

Electrostatic shielding of nonsequential disc windings in transformers
TL;DR: Transformer coils wound with disk winding sections nonsequentially arranged are provided with shields between the turns of mechanically adjacent sections to increase the series capacitance of the winding as mentioned in this paper, allowing a reduction in insulation between the individual winding turns and between the winding discs.
