Question 1 of 10
What is the primary function of the core in a transformer?
The core provides the path for the magnetic flux, enabling energy transfer between the primary and secondary windings.
Question 2 of 10
What is the purpose of the oil in an oil-filled power transformer?
The oil serves as both a coolant and an insulator, preventing overheating and electrical breakdown.
Question 3 of 10
What is the role of the cooling tubes?
Cooling tubes increase the surface area for heat dissipation, helping to maintain the transformer's operating temperature.
Question 4 of 10
Which component stores extra oil to accommodate temperature changes?
The conservator maintains the oil level as the oil expands and contracts due to temperature variations.
Question 5 of 10
What is the function of the Buchholz relay?
The Buchholz relay detects internal faults, such as insulation breakdown or arcing.
Question 6 of 10
What do bushings provide?
Bushings provide insulated entry and exit points for the high-voltage conductors.
Question 7 of 10
What is the purpose of the pressure relief valve?
The pressure relief valve protects the transformer from overpressure caused by internal faults.
Question 8 of 10
What do oil level indicators monitor?
Oil level indicators provide a visual indication of the oil level in the transformer tank.
Question 9 of 10
Where are the primary and secondary windings located?
The windings are wrapped around the core, allowing for magnetic flux linkage.
Question 10 of 10
What is the main tank primarily designed to do?
The main tank contains the insulating oil that surrounds the transformer components.
