1. A hydroelectric-generating plant uses ? to generate water flow
electricity? water pressure
2. Which type of power source is typically located on Secondary
or near customer facilities, requires little distribution
infrastructure, and supplies power in the event of an
interruption in power from the electric utility?
3. Which of the following electrical loads are required by Egress lighting
governing entities to have secondary power sources? Fire pumps
4. What percentage of electricity is produced from nu- 19%
clear power?
5. ? are the most commonly used source of secondary Engine generators
power.
6. Net metering uses one meter that can measure power T
usage in either direction (importing or exporting), ef-
fectively subtracting exported electricity from import-
ed electricity. This determines the net electricity con-
sumption of the utility customer.
7. What is the last point on the power distribution system The switchboard
for the power company?
8. The terms "step-up transformer" and "step-down voltage
transformer" describe an increase or decrease in ? .
9. An overcurrent protective device prevents ? from conductors or devices
reaching excessively high temperatures, due to high
currents, by opening the circuit.
10. Electrical demand
