Answer the following statement(s) true (T) or false (F)
1. All phase windings within the transformer normally have the same relative polarity. 2. Terminal markings indicate all the relationships between primary and secondary. 3. Most three-phase, dry-type distribution transformers are connected as a primary wye connection. 4. If the pattern is a delta-delta pattern, the displacement must be 60°. 5. It is only necessary to connect the similarly marked high- and low-voltage terminals if the transformers have the same voltage ratio, the same percent impedance, and the same angular displacement.
