Метод измерения вебер-амперной характеристики электротехнических устройств

The article suggests a method of measuring weber ampere characteristics of electrical devices without use of special means of measurements. This method consists in the fact that the coil electrical device is a sinusoidal voltage with the specified frequency and measured amplitude of the harmonics of a flowing current. On the basis of these data, with the help of a mathematical model to define the parameters of a polynomial describing weber ampere characteristic of the magnetic electrical device. Magnetic properties of the magnetic circuit largely determine the performance characteristics of electrical device. On the basis of the proposed method can be implemented device with the use of applied programs: MicroCap, Statistica, LabView, which can be used in the systems of control of technological process of manufacture of electrotechnical devices. Application of the developed method makes it easy to run measuring operations while maintaining an acceptable accuracy.
