Why is the polarity of the output and input is same in ac transformer?
polarity play essential role in protection purpose if you have done wrong polarity in yours system then protection will operate under normal operationFurther AnswerThe polarity of a single-phase transformer describes the phase relationship of the secondary voltage relative to the primary voltage. Polarity is described as being either 'additive' or 'subtractive'. Knowing a transformer's polarity is one of the essential requirements for paralleling a pair of individual transformers.
