In a magnetic circuit, the medium of transformation of induced voltages and current plays a vital role in study of Hysteresis. It is necessary to study the Hysteresis to evaluate the performance of this media for electrical characteristics. Often the transformation media in electrical circuit is a transformer either for step-up or step-down purposes. The magneto-motive force “H” is a direct function of the exciting current and the flux density “B”. It is integral of the applied voltage.
In this trainer, it is attempted to study and demonstrate the above mentioned principles. This trainer permits to view the BH curve on the oscilloscope for various currents. This trainer has necessary components to like transformer under study, Isolation transformers, passive components, Ammeter and Voltmeter. An external Variac, continuously variable in the range of 0 to 270V @ 3A is necessary.
NOTE: Since low power transformer is used in this trainer, large power measurements beyond 10W cannot be made.
