Core of Transformer and Design of Transformer Core finland transformer tank building volume

May 30, 2019 · Purpose of Transformer Core. In an electrical power transformer, there are primary, secondary and sometimes also tertiary windings. The performance of a transformer mainly depends upon the flux linkages between these windings. For efficient flux linking between these windings, one low reluctance magnetic path common to all windings should be provided in the transformer.DESIGN OF TRANSFORMERTransformer may be designed to make one of the following quantity as minimum i. Total volume ii. Total weight iii. Total cost iv. Total loss All these quantities vary with ratio r = m/ AT.
