Electrical Testing at Elevated Frequency of Stator Cores and Exciter Circuits
... The measurement is performed at a frequency of 500 Hz, as significantly lower power is required at high frequency than at grid frequency (50 or 60 Hz) to generate equivalent magnetization losses in the stator core. However, since the stress on the insulation between the laminations is comparable, th ...
