You cannot 'reverse' the polarity of a transformer -it is either wound with 'additive polarity' or 'subtractive polarity', and there's not much you can do about it!
For a single transformer, its polarity doesn't really matter. But if you are going to parallel two Transformers, then you must know the polarity of each transformer in order to avoid harmful circulating currents in their secondary windings.
a polarity test is a test which use to check the polarity of tranformer.the rision of this test to running the two or more transformer in parallel.like bettry situation or to fin the terminals
when two transformer are connected in parallel condition,and the polarity of transformer are opposite to each other then a large circulating current flow through out the winding,therefore a very small current flow thro, the load .therefore lifespan of transformer will be reduced.
Yes in AC circuits the terminology reversed polarity means the hot and neutral are reversed to what they should be. In DC circuits reversed polarity means that the positive and negative terminals are reversed to what they should be.
yes.you can get 5v output even when the polarity is reversed. In a 5v battery, if u reverse the polarity, then u'll get the same 5v as output , but in the opposite direction.(i.e.,)-5v(negative 5 volt
Yes, polarity is always important. Many under cabinet fluorescent fixtures are small enough to use a small transformer rather than a ballast. But even then, the transformer will have a longer life if it's wired with correct polarity.

Knowing the polarity of transformers is important if they are to be connected in parallel.

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.
