Zusammenfassung: | No-load losses
P of transformers core have been considerably decreased through introduction of the so-called multi-step-lap designs. However, profound guidelines for the optimum step-number
N do not exist. This study shows that the combination of both
N and working induction
B characterises the flux distribution. Transformer cores can operate in an over or an under-critical way depending on
N and
B. |
