Question 1 of 10
Which of the following is a key design factor for transformers?
Protection against internal and external faults is a critical design consideration for transformers.
Question 2 of 10
What is the primary function of transformer oil?
Transformer oil serves as an electrical insulator within the transformer.
Question 3 of 10
What is a major cause of oil degradation?
Contamination is a significant factor in the degradation of transformer oil.
Question 4 of 10
What can indicate oil failure?
Gas formation in the oil is a common indicator of oil failure.
Question 5 of 10
What can cause overheating in the transformer core?
Defective core insulation or conducting bridges can cause overheating.
Question 6 of 10
What is the result of mechanical impacts exceeding 3g on the core?
Mechanical impacts above 3g can distort the transformer core.
Question 7 of 10
What is a common winding fault?
Short circuits between turns of the winding are a common type of fault.
Question 8 of 10
What forces do windings experience?
Windings are subject to radial and axial forces.
Question 9 of 10
What is the permissible temperature for transformer oil at rated load?
The permissible temperature for transformer oil is 65°C.
Question 10 of 10
What can cause overheating beyond manufacturer specifications?
Overheating can be caused by both overloads and external short circuits.
