Refined calculation of inductive parameters of linear current transformers.
Abstract
A method has been developed for calculating inductive parameters (intrinsic and reciprocal) using a computer program for calculating the plane-parallel field of current transformers, whose magnetic cores have non-magnetic gaps. It is shown that the accuracy of the technique depends on the sectoral imposition of the secondary winding and does not exceed 20% at sectoral 120 ° and 10% at sectoral 240 °, for uniform secondary winding the calculation accuracy is ± 5%.
