Answer the following statement(s) true (T) or false (F)
1. For the primary side of the delta bank, the line voltage and the coil voltage are the same. 2. The three single-phase transformers used in a delta-wye connection have different kVA capacities. 3. The delta-wye transformer bank is well adapted for stepping up voltages. 4. The open-wye–open-delta transformer connection is sometimes used to deliver small amounts of three-phase power to a secondary load and deliver larger amounts of single-phase power to the secondary load. 5. Three-phase transformers may only be connected in delta-delta and wye-wye.
