The Comparison of Magnetic Values Obtained from Hall Probes and Measuring Coils in Synchronous Generators

This article gives a review of a part of measuring results obtained during factory tests and inspections of a wind mil power unit. Magnetic fields were measured by two different measuring methods and the results were compared consecutively. The article also gives the results of calculation of dynamic electromagnetic field by application of FEM to the model of a synchronous generator installed in the wind mill power unit. Those results were compared to the measuring results as well.
