ABSTRACT:
Disclosed herein is a technique for calibrating a transformer element, comprising the steps of providing a transformer element with a primary winding and a secondary winding; providing a memory to store a range of expected values of a power component, each value being representative of a flow of power expected through the secondary winding for a corresponding flow of power through the primary winding; establishing a flow of power at a first level through the primary winding, thereby to establish a corresponding flow of power through the secondary winding; measuring the power component for the flow of power through the secondary winding to obtain a first measurement thereof; comparing the first measurement with a corresponding expected value and calculating a first factor according to the difference there between; and storing the first factor; varying the flow of power in the primary winding to a second level; measuring the power component for the flow of power through the secondary winding to obtain a second measurement thereof; comparing the second measurement with a corresponding expected value and calculating a second factor according to the difference there between; and storing the second factor.
