Transformer Phase Relation

This test will detect if transformers have been connected in a correct phase relationship. It calculates the angular displacement and relative phase sequence of the transformer, and can be tested at the same time as ratio and polarity tests. The voltages of the phase of primary and secondary can be recorded and comparisons made to get the phase relation.
