For the parallel operation of two single phase transformers it is necessary that they should have ________

For the parallel operation of two single phase transformers it is necessary that they should have ________ Correct Answer same polarity

Polarity of the two transformers must be same if the are supposed to be operated in parallel mode of operation. It is okay if they have unequal efficiencies, or unequal kVA ratings, as parallel connection is still possible.
