Learning

Learning mode has no timer. After answering, you see feedback and the correct options. You can return to a question and repeat a topic.

Exam

A practice exam lasts up to 60 minutes and includes up to 50 questions from the selected collection. Correct answers and results appear after completion.

Sample questions and answers

These examples come from the published collection. Choose Learning to study questions in sequence, or Exam to check your knowledge.

Which control mode is recommended during manoeuvring?

One correct answer

  • Optimal, because this mode allows an increased load of the generators during manoeuvring
  • Equal, because of the wider control range which allows the low priority generator(s) to be connected at low loads✓ Correct answer
  • Cyclic, because the risk of fouling of intake channels are eliminated, and because of this the risks of reduced capacity of the generators are minimised
What will happen if Load dependent start/stop of generator sets is in auto mode?

One correct answer

  • It will start/stop the generator sets in response to varying load✓ Correct answer
  • It will start/stop the generator sets in response to fuel consumption
  • It will start but never stop the generator sets in response to varying load
  • It will stop but never start the generator sets in response to varying load
The kW and kVAr instruments on the main switchboard reads respectively 630 kW and 400 kVAr. What is the actual power factor?

One correct answer

  • 0.8
  • 0.85✓ Correct answer
  • 0.9
How could you monitor the correct instant for synchronising without the aid of a synchroscope or synchronising lamps?

One correct answer

  • By connecting a pair of voltmeter probes across one phase of the incoming generator circuit breaker, and then adjusting the generator speed until the voltmeter slowly fluctuates from zero to maximum. Connect the breaker when the voltmeter passes through zero✓ Correct answer
  • It is not possible to synchronise generators without the synchronising aids
  • By off-loading the running generator to a minimum to avoid large "kicks" at connection. Adjust the incoming generator to a frequency slightly less than the running generator. The running generator will then "pull" the incoming generator into synchronism
Which statement is true?

One correct answer

  • The Priority 1 generator will be first IN / first OUT
  • The Priority 1 generator will be first IN / last OUT✓ Correct answer
  • At Cyclic control mode the generators change Priority order

Guest access lasts 23 minutes. Free registration lets you continue without limits, save progress and review mistakes in your account.

What language are the questions in?

Questions and answer options retain the language of the original bank. You can change the interface language separately.

Can I use my result as an official document?

No. This is independent practice. A result does not replace an examination, certificate or knowledge check by an authorised organisation.
