Title:
METHOD AND DEVICE FOR SUBSTANTIALLY REDUCED ELECTRICAL GROUND DISPLACEMENT CURRENT GENERATED BY WOUND PART
Document Type and Number:
Japanese Patent JP2002280242
Kind Code:
A
Abstract:

To substantially reduce the capacitive displacement current between transformer input winding and transformer output winding.

The transformer has an input winding and an output winding. In one embodiment, the transformer input winding is capacitively coupled with the transformer output winding. The transformer is capacitively coupled with an electrical ground. One or more additional windings are introduced in as one part of the transformer. One or more additional windings-substantially reduces the capacitive displacement current between the transformer input winding and the transformer output winding, by taking the relative balance of a static electric field generated between these winding and/or between the transformer and an electrical ground, thereby eliminating the static electricity generated by all windings within the transformer with respect to the electrical ground by the selection of the physical arrangement of the additional winding and the number of windings.
