... An electric generator or electric motor consists of a rotor spinning in a magnetic field. The magnetic field may be produced by permanent magnets or by field coils. In the case of a machine with field coils, a current must flow in the coils to generate the field, otherwise no power is transferred to ...

INSTRUMENT TRANSFORMER DIMENSIONING FOR SUBSTATIONS Ronny Mustajärvi
... One important factor that determines the saturation point is the accuracy limit factor or ALF. ALF times the rated primary current is the saturation point where the iron core begins to saturate as seen in Figure 2. The physical size of the iron core greatly depends on the accuracy limit factor. The ...
