ABSTRACT:
An electrostatic shield and a voltage transformer having a high voltage winding and a low voltage winding. The shield takes the form of a concentric winded coil, made from a round conductive wire having a layer of insulation around it and a radius of at least ten times the radius of the wire used for the high voltage winding. This shield is dimensioned to surround the high voltage winding of the transformer.
