Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Atoms that have acquired an electrical charge






2. Are used to supply power to smaller industrial and commercial users as well as residential customers. These lines can be compared to local roads such as the one in your local area or neighborhood - i.e. they're designed to handle the needs of local t






3. Any path that electrons flow through






4. An energy storage device that converts chemical energy to electricity when power is needed.






5. An electrode where free electrons are produced






6. A fundamental quantity in electricity (+ or -)






7. A material in which charge moves through easily






8. Used to supply power to large industrial and commercial facilities as well as the Retail System. lines can be compared to state highways and major roads around cities.






9. Negatively charged particles of an atom






10. A material that has no resistance to electrical current - this usually occurs near absolute zero






11. A device that changes mechanical energy into electricity






12. V=IR.


13. Similar to switchgear except for use in low voltage versus medium voltage applications. used to supply power to motor control centers and large individual low voltage motors in some applications.






14. A circuit with a break in its path






15. Are used to provide low voltage circuits for use in metering - monitoring - and protective relaying applications. The turns ratio of the transformer determines the low voltage rating as a function of the system voltage - and is often selected to be 1






16. The flow of electrons






17. Used to convert mechanical energy to electrical energy coupled to the turbine shaft






18. If you are requesting service for new loads - or are making changes that affect the time when a load would operate or the amount of load -






19. May be used to power various low voltage loads and are typically used for applications that do not require any form of remote control.






20. Analogous to a power plant switchyard but on the load end. Voltage is stepped down to Distribution System voltages.






21. Changes in voltage caused by motor starts or other loads being switched onto an electrical system






22. Power Systems Branch [Position] one required nuclear utilities to install degraded grid voltage relay schemes to preclude connecting safety related loads to the grid following an accident if grid voltage should be inadequate to support required opera






23. Are used to provide low current circuits for use in metering - monitoring - and protective relaying applications. The turns ratio determines the amount of current that will be available in the secondary as a function of the system current on the prim






24. A voltage source that does not change polarity such as that delivered from a battery.






25. The path of an electron in an atom or molecule






26. The power output from the plant is stepped up in voltage to match the grid voltage. Transformers that are used to provide offsite power to the plant (e.g. when the generator is off-line) step down the voltage.






27. One or more cells connected in series






28. Neutral charged particles of an atom






29. Is the vector sum of real and reactive power in an AC circuit and is measured in volt-amperes.






30. Used in numerous applications to amplify or perform switching operations.






31. Voltage is stepped down again to serve smaller industrial and commercial customers as well as residential needs.






32. Changes the voltage of electricity so that it can be transferred over long distances






33. Is a configuration used for very high current bus assemblies typically operating at generator voltage levels of 20 to 24 kV where each conductor is mounted within its own enclosure.






34. Main Generator feeds main transformer - aux transformer (to aux loads) and crosstie to train B






35. (analogous to flow) predominantly flows on the surface of the conductor.






36. The flow of electrons (-) through a material






37. A solid conductor through which a current enters or exits a medium






38. High voltage breakers and buses are arranged to allow power flow on the grid while isolating individual generators - transformers or transmission lines as needed. Power from the plant is delivered to the grid via the plant ****** - and the ******* se






39. Used to optimize power output. Multiply by root 3.






40. A mechanical switching device used to either enable or interrupt current flow in a circuit. Typically provides both overload and fault protection. Is similar to a fuse; however - can be reset and reused.






41. Is typically used for medium voltage applications where the 3 phase conductors can be mounted within the same enclosure.






42. A material that dissolves in water producing a solution that conducts electricity






43. Voltage Source - Conductor - Switch - Load






44. Requires - in part - that (1) electric power from the transmission network to the onsite distribution system shall be supplied by two physically independent circuits (not necessarily on separate rights of way) designed and located so as to minimize t






45. 125 and 250 VDC.






46. An electrode where reduction occurs






47. Voltage is stepped down again to serve smaller industrial and commercial customers as well as residential needs.






48. An assembly of low voltage circuit breakers and/or starters used to supply individual loads of small to moderate sizes. Each feeder circuit is typically contained in a separate compartment or bucket.






49. Is measured in watts and represents the power consumed by the resistive elements in an AC circuit






50. Nuclear fuel is used to produce heat which is used to create steam. The steam is used to spin the turbine. The turbine shaft is connected to the generator rotor. The mechanical energy is converted to electrical energy through the generator.
