Block 1 - Meggers, Smoke Spot Testing, Emissions Requirements Flashcards
What is the primary purpose of a Megger?
Test the insulation quality of electrical circuits
What is the importance of discharging capacitance after an insulation resistance test?
To prevent electric shock hazard
Why is regular insulation testing important in high-voltage systems?
To prevent catastrophic insulation failure
What type of protective measure should be taken when testing motors with a Megger?
De-energize the motor
Which insulation level is considered “Critical” based on Megger test readings?
2 - 5 Megohms
What is the main cause of most electrical motor failures?
Insulation breakdown
Which voltage setting for a Megger is used for insulation testing on low voltage motors (208-600 VAC)?
500 Volt
What is the best reading from a Megger during an insulation test?
OL (Open Line)
Which of the following is a benefit of using a Megger for insulation testing?
Preventing short circuits by verifying insulation quality
Which of the following is used to prevent reenergization of electrical power systems during testing?
Temporary protective grounds
What can high levels of soot in the oil burner exhaust lead to?
Reduced heat transfer
Which of the following is NOT a manufacturer of smoke spot test equipment?
Makita
What is the purpose of a smoke spot test for fuel oil fired heating equipment?
Identify complete combustion
Which smoke level is generally considered acceptable for most oil burners?
0 to 1
What should be done to the smoke tester if it still measures smoke after two atmospheric tests?
Disassemble and clean it with warm water and detergent
What does a smoke level of 0 on the Bachrach/Bosch scale indicate?
No black soot visible
Which type of tester can also produce a smoke level number without the use of a hand-operated pump?
Electronic soot tester
What is indicated by a yellow tint on the smoke test dot?
Unburned raw fuel escaping the flame
What is a common misconception about oil-fired appliances and CO production?
They cannot produce CO without visible smoke
How is the smoke test conducted?
By drawing flue gases through a filter paper with a vacuum sampling pump
What is the primary regulation governing methane emissions in Canada?
Federal Greenhouse Gas Pollution Pricing Act (GGPPA)
Which of the following sectors has specific federal regulations aimed at reducing methane emissions?
Oil and Gas
What activities in the oil and gas sector are targeted by federal methane emission regulations?
Venting, flaring, and fugitive emissions
What is the purpose of monitoring and reporting systems in the oil and gas sector regarding methane emissions?
To track and report methane emissions for transparency and accountability
