WebMay 26, 2024 · Modern core materials have high relative permeability, in the order of several thousand. The core permeability only affects the magnetizing inductance, not the leakage, so you can see how the ratio of 1% is a very arbitrary number. Figure 7: One of the Very Misleading Assumptions About Leakage Inductance. Don’t fall into this trap. WebWith less inductance in the primary winding, there is less inductive reactance, and consequently a much larger magnetizing current. A substantial amount of the current through the primary winding merely works to magnetize the core rather than transfer useful energy to the secondary winding and load.
WebClearly we do not want this to happen in a transformer, otherwise the magnetizing inductance will then become virtually a short-circuit. A φ B = and B sat-B sat. 21 Core materials Apart from saturation, hysteresis is an important aspect. The “hysteresisloop”shown here is in a “piece-wise linear ”form. WebAug 9, 2024 · Magnetizing inductance has been measured using a static DC excitation technique, which can be employed whenever the neutral point of the machine is accessible . This approach is not applicable when the neutral point of the machine is inaccessible. ... As shown in Fig. 7c, the magnetic saturation of the iron core leads to a reduction in the ...
