MAGNETIC FLUX SCATTERING IN TRANSFORMERS

Existing methods do not allow measuring leakage reactance for each transformer winding separately, therefore, for simplicity, they are often assumed to be equal to each other. The purpose of the study is to substantiate the possibility of experimental determination of leakage reactance for each transformer winding separately. The dissipation reactance of each transformer winding separately can be determined by at least three experimental methods that give satisfactory agreement of the results. An almost paradoxical result – the capacitive nature of the leakage resistance of the inner winding of the transformer was obtained only for concentric cylindrical windings. It should not be generalized to other types of windings. The presented experimental methods are not tied to the character of the leakage resistance reactivity. They are universal - they can be used with any type of winding. The results obtained are recommended for use in the design and study of transformers.
