FAQ
Why polarity test has to be done in a transformer?
Polarity test is must for transformers when parallel operation is done. Because while doing parallel operation, if you connect terminals of opposite polarity, it will result in a dead short - circuit. So, to connect the same polarity windings together both in primary and secondary, polarity test is done.
