Abstract
Embodiments described herein comprise a current transformer having a primary winding with multiple primary parallel branches that divide the primary current, and a secondary winding which is placed in any one, or more, branches. The current thus divided in the primary branches produces an alternating magnetic flux which induces alternating current in the secondary winding for an end user application. The invention disclosed herein reduces the weight and size of the current transformer drastically compared to the existing conventional current transformers.
Claims15
A current transformer, comprising:
- a magnetic core;
- a primary winding configured to carry a primary current wherein the primary winding comprises at least a First group of primary winding branches and a second group of primary winding branches connected in parallel;
- one or more secondary windings wound around the core, and magnetically coupled to at least one of the primary winding branches, each secondary winding having a plurality of turns configured to induce a secondary current from at least one of the one or more of the primary winding branches;
- and
- an end user coupled to the secondary winding.
A method of reducing a current to an end user comprising:
- flowing a primary current through a primary winding in a current transformer;
- dividing the primary current between a plurality of primary winding branches which are in parallel in the primary winding;
- inducing a secondary current in at leas one secondary winding from one or more of the primary winding branches;
- and
- sending the secondary current to the end user.
