Polarity in transformers refers to the relative direction of the voltages in the primary and secondary windings. It is important when transformers are connected in parallel or in certain phase-sensitive applications.
Calculation
To check polarity, a voltmeter is used to measure the voltage difference between the primary and secondary terminals (usually one terminal from each is temporarily connected together). The resulting voltage reading helps determine whether the windings are in additive or subtractive polarity configuration.
Other options like a short-circuit test or input current measurement are not used for polarity verification.
