The influence of the short-circuit location in active sheet steel on the diagnostic parameters of a turbogenerator during its electromagnetic tests

摘要

Basic relations that characterize the diagnostic parameters of the active sheet steel of turbogenerators during their electromagnetic testing using circular magnetization with a small current (with an induction in the core back of about 0,01-0,05 T) are described. These parameters are estimated depending on the location of shorting of the sheets of active steel of the machine. Location of shorting of the sheets of active steel of the machine. The results obtained can be used to improve the technique of electromagnetic tests.
