Fill in the blank(s) with the appropriate word(s).
Answer the following statement(s) true (T) or false (F)
1. Potential transformers have ratings from 1,000 to 5,000 volt-amperes (VA). 2. Current transformers are used so that ammeters and the current coils of other instruments and relays can be connected directly to high-current lines. 3. The power factor is equal to the power in kilowatts multiplied by the apparent power in kilovolt-amperes. 4. On a three-phase, three-wire system, two potential transformers of the same rating and two current transformers of the same rating are necessary. 5. In a three-phase, four-wire system, both the interconnected potential and current secondaries are grounded to protect against possible high-voltage hazards.
