Toroidal fixed transformers have significant advantages over conventional transformers: their construction results in up to 50% less volume and low weight. Since the ring cores have almost no air gap, only a very low magnetic stray field is produced and the transformers are almost hum-free. The change in secondary voltage between idling and full load is much smaller than with transformers with a nested core.
