Abstract
Possibilities of a leakage inductance calculation of high-voltage measurement transformer and autotransformer windings for the purpose of the further use of results at definition of their characteristics on corresponding equivalent circuits are observed. It is offered a leakage inductance calculation model for cylindrical windings of magnetic systems by means of the software which uses numerical methods of finite elements. It is offered formulas of a leakage inductance calculation with use of the data numerical calculation. Calculated curves which correspond to certain levels of a leakage inductance of windings are gained. The developed method of an effective leakage inductance calculation can be applied to sampling of magnetic systems equivalent circuits both transformer, and autotransformer type. This method allows using various software packages of calculation by a finite elements method. References 2, figures 2.
