Power Engineering 3

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. 1. process 2. measurement 3. automatic controller 4. final control element






2. The offset of a proportional controller decreases to maintain SP






3. Power in watts






4. Opposition to liquid head pressure






5. There is no relative movement between the rotor bars and teh flux of the rotating field - countacts speed changes






6. Range of 250mm water to 350kPa






7. Pipe thickness must be increased by 15% or 3.0mm






8. Exactly the theoretically amount of air necessary was supplied and the combustibles were all completely burned






9. Oscillate - on - off control behavior






10. Can act as an induction motor - 3 directional inverse time overcurrent relays






11. Cannot be over 75m away from building - average of 12.2m away from building






12. Flammables and combustibles






13. Supervisory control and data application






14. Ananolg input - everchanging signal






15. Controller output is above minimum value when error is zero






16. Heavy load deman






17. Causes current to lag behinde the applied voltage by 90 degrees






18. Takes into consideration the speed at which the variable is deviating from the SP - only occurs when there is a change in error rate






19. Conductor being moved - 'cut' magnetic fields of flux relative to the conductor movement - using fleming's right hand rule






20. 'hops'






21. Any 2 conductors seperated by an insulating material - unit if farad (F) - symbol used 'C'






22. PLC control diagram






23. Second element of WHMIS






24. Shunt - series and compound wound






25. Parallel branches - 2 series of resistors - the bridge indicates a balanced voltage condition






26. Thermocouple connected in series






27. Ground faults






28. Negatively charge particles using high voltage DC charged particles - 95% + efficiency






29. Help reverse the current int eh coil passing under the brushes - commutations






30. Self excited - armature fields conencted in series - initial emf depends on residual magnetism - field current is also the load current






31. Occurs when some of the elements pass to the stack






32. The flow of power pulsates






33. Conencted to transformers or inside switchgears






34. Voltage decreases with an increase of load current






35. Allows control from one location






36. Pulse generator operates at 3-40kHz






37. Canadian Standard Association (CSA) - American Society of Mechanical Engineers (ASME) - National Board of Boiler and Pressure Vessel Inspectors (NBBI)






38. Lower flash point the gas






39. Imaginary power






40. Organically bound component of the fuel






41. Smallest cross sectional area






42. 1.product information 2. hazardous ingredients 3. physical data 4. fire and explosion data 5. reactivity data 6. toxicological data 7. preventive measures 8. first aid 9. preperation information






43. Determines the % of moisture - volatile material - fixed cardon and ash - buring qualities






44. 85% or less of normal value power






45. Corrosive materials






46. % moisture - fixed carbon






47. RTU (remote terminal unit) and MTU (master terminal unit) - modems or data communication equipement (DCE)






48. The fule - the method of firing - the burner and furnace design and load on boiler






49. Is the combined effect of inductive reactance and capacitive reactance






50. Combination of shunt and series
