It just means that the transformer is being used at other than the design optimum. The bottom line is that for continuous operation, the rated voltage for a power transformer should be respected for ...

The basic inductive arrangement of the differential transformer with a movable magnetic core can be developed for operation at any AC frequency in the range from 60 cps to 20,000 cps. When using the ...

This trend continues as the transformer power level increases and it is independent of core material and frequency of operation. Figure B shows a comparison of temperature rise attributable to ...
