The effect of high flux values is the symmetrical saturation of the iron core of the generator or
that of the unit transformer. During saturation, the magnetizing current is high and distorted;
high current peaks can be detected. The odd harmonic components of the current are of high
magnitude and the RMS value of the current also increases. The high peak values generate
high dynamic forces, the high RMS value causes overheating. During saturation, the flux
leaves the iron core and high eddy currents are generated in the metallic part of the generator
or transformer in which normally no current flows, and which is not designed to withstand
overheating.
