Reactance and Eddy Current Loss in Toroidal Transrormatoric Devices-I

Calculation of the reactance of toroidal windings must be carried out in a way different from cylindrical windings if any accuracy is to be attained. Energy stored in the leakage inductance can expressed by a triple integral. This is reduced to planimetering in the enlarged cross-sectional drawing and two successive tabulated summations. A numerical example is presented in the form of a tabulated calculation which can be computerized easily.
