CHARACTERIZING MAGNETIC MATERIALS USING VIRTUAL INSTRUMENTATION

• Abstract:

  A virtual instrumentation based scheme is developed for the characterization of magnetic materials. The principle used for measurement is derived from the comparison method of testing instrument transformers. A prototype has been developed by suitably modifying an instrument transformer test set. Characterization of magnetic materials at single frequency and multiple frequencies have been carried out. Typical test results obtained are presented in the paper. The developed instrument substantially reduces the testing time associated with magnetic characterization.
