Abstract
A transformer characterized by groups of low voltage and high voltage windings inductively related to a core member, and a shunt of magnetizable microlaminations disposed between the low and high voltage windings, whereby the shunts independently adjust the transformer impedance.
Claims8
An electrical power transformer comprising:
- a core member;
- groups of sectioned low voltage windings and of high voltage windings which windings are inductively related to the core member;
- a shunt of magnetic material between each group of low voltage windings and the high voltage windings;
- and
- each shunt comprising microlaminations of magnetic materials.
