Answer the following statement(s) true (T) or false (F)
1. When three single-phase coils are connected so that each coil is connected to the beginning of another coil, a simple open-delta system is formed. 2. Never complete the last connection if there is a voltage difference greater than zero. 3. In any closed-delta transformer connection, the line voltage and the voltage across the transformer windings are the same. 4. The high-phase situation can be a serious hazard to human life as well as to any 120-volt equipment connected improperly between the high phase and neutral. 5. A three-phase transformation of energy is not possible using only two transformers.
