medium
10 Questions
Question 1 of 10
What is the primary reason for performing live line washing or cleaning on energized power lines?
Contaminants like dust, salt, and pollutants can reduce insulation and cause flashovers.
Question 2 of 10
What type of contaminants are particularly problematic for power lines, often necessitating live-line washing?
Industrial pollutants and salt are conductive and can create leakage currents, reducing insulation strength.
Question 3 of 10
During live line washing, what is the typical fluid used for cleaning?
Deionized/distilled water has very low conductivity to prevent short circuits.
Question 4 of 10
What is the key advantage of performing live line washing compared to de-energizing the lines for cleaning?
Avoiding outages is a major benefit for maintaining service reliability.
Question 5 of 10
What type of equipment is typically used for live-line washing?
Specialized equipment ensures safety by maintaining insulation during the process.
Question 6 of 10
What potential hazard is minimized by using deionized water during live line washing?
Deionized water's low conductivity minimizes the risk of electrical shock to workers.
Question 7 of 10
Which of the following environmental conditions often necessitates more frequent live line washing?
High humidity combined with pollutants creates conductive films on insulators.
Question 8 of 10
What is the purpose of the insulated equipment used during live line washing?
Insulation prevents the current from flowing through the worker's body.
Question 9 of 10
Besides insulators, what other components of power lines might be cleaned during live line washing?
All components may accumulate contaminants and benefit from cleaning.
Question 10 of 10
What is a common safety precaution taken before starting live line washing?
All options are crucial for ensuring the safety of the crew.
