EEI TECH EEI Tech Reading Comprehension 2 — Questions and Answers
Question 1: A log entry reads: 'Breaker 14 tripped twice in 24 hours; cause undetermined.' What does 'cause undetermined' mean?
- The cause is obvious
- The cause has not been identified (Correct answer)
- The breaker is repaired
- The breaker should be replaced
Correct answer: The cause has not been identified
'Undetermined' means not yet identified or established.
Question 2: A work order states: 'Replace defective capacitors in Unit 3 only.' A technician notices Unit 4 also has a defective capacitor. What should the technician do?
- Replace Unit 4's capacitor too
- Ignore Unit 4
- Report the Unit 4 issue to a supervisor (Correct answer)
- Replace all capacitors in both units
Correct answer: Report the Unit 4 issue to a supervisor
The work order is limited to Unit 3; the proper action is to report additional defects through proper channels.
Question 3: A procedure says: 'If voltage exceeds 130V, shut down immediately and notify the control center.' Voltage reads 132V. What is the correct action?
- Continue monitoring
- Reduce load and continue
- Shut down and notify control center (Correct answer)
- Reset the voltmeter
Correct answer: Shut down and notify control center
132V exceeds 130V, so the procedure requires an immediate shutdown and notification.
Question 4: A safety bulletin reads: 'Arc flash incidents account for the majority of electrical fatalities in utility work.' What is the MAIN point of this statement?
- Arc flash is rare
- Arc flash is a leading cause of electrical deaths (Correct answer)
- All electrical work is equally dangerous
- Fatalities are unavoidable
Correct answer: Arc flash is a leading cause of electrical deaths
The statement identifies arc flash as causing the majority of electrical fatalities, making it a primary safety concern.
Question 5: A schedule reads: 'Lubrication: monthly; Inspection: quarterly; Full overhaul: annually.' How many inspections occur per year?
- 1
- 2
- 3
- 4 (Correct answer)
Correct answer: 4
Quarterly means every 3 months, so 12 ÷ 3 = 4 inspections per year.
Question 6: A passage states: 'The relay is designed to interrupt current flow when amperage exceeds the preset threshold.' What does the relay do?
- Increases current
- Measures voltage
- Stops current when it is too high (Correct answer)
- Stores electrical energy
Correct answer: Stops current when it is too high
The relay 'interrupts current flow' when amperage exceeds the threshold, meaning it stops the current.
