Comparison between measured and computed magnetic flux density distribution of simulated transformer core joints assembled from grain oriented and non-oriented electrical steel
The flux distribution in an overlapped linear joint constructed in the central region of an Epstein Square was
studied experimentally and results compared with those obtained using a computational magnetic field
solver. High permeability grain-oriented (GO) and low permeability non-oriented (NO) electrical steels
were compared at a nominal core flux density of 1.60 T at 50 Hz. It was found that the experimental results
only agreed well at flux densities at which the reluctance of different paths of the flux are similar. Also it
was revealed that the flux becomes more uniform when the working point of the electrical steel is close to
the knee point of the B-H curve of the steel
