... consideration of non- consecutive rotor bar breakages in MCSA was dealt with [25]. This research mentioned that the ratio between the amplitude of the left sideband harmonics in the cases of double and single bar breakage coincides with the ratio between the amplitudes of the pth inverse flux density components of the fault field. Besides ...

... the saturation due to the lack of effective severe conditions. If saturated, the transformer will overheat direct signal gathering of the magnetic strength or the and generate harmful harmonics to the grid. The measurement of the dynamic magnetic flux is an effective method to observe magnetic flux in transformer iron cores [13-15]. At present ...
