Rudevich N. Reduction of the errors caused by high-voltage transformers of a current and voltage, joining to their secondary chains of compensating devices.

Research object: high-voltages measuring transformers of current and tension. Research purpose: development of compensating devices tacking of which to the second chains of high-voltages measuring transformers of current and tension allows to decrease errors, which conditioned by measuring transformers. Research methods and apparatus: substantive provisions of theory of electric chains, mathematical model of processes in the ferromagnetic mandrel of measuring transformers, method of small parameter, for the decision of differential nonlinear equalization, decomposition of functions in the row of Тeylora. Theoretical and practical results: the charts of devices of electronic indemnification of errors of high-voltages measuring transformers of current and tension are developed, the algorithms of calculation of parameters of elements of devices of electronic indemnification of errors of high-voltages measuring transformers of current and tension are developed. Novelty: the method of electronic indemnification of error of measuring transformer of tension which is based on comparison of the second tension of transformer with the second tension of compensating measuring transformer of tension is improved, from existing he differs to those, that tension is formed for the selected part of loading, that does him suitable for a high-voltage transformer; the method of electronic indemnification of error of measuring transformer of current which is based on forming of current of magnetizing of transformer and correction to them results of transformation is improved, from existing he differs to those, that correction is carried out for the selected part of loading, that does him suitable for a high-voltage transformer; grounded correlations of parameters of compensating devices for the selected part of loading of measuring transformers of current and tension, which complete indemnification of errors is achieved at. Degree of introduction: a firm is "Electro-sphere". Sphere of the use: electroenergy.
