Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A large transformer dissipates 100 kW of heat during peak operation. Determine which cooling method would be most appropriate for this transformer and justify your answer.

💡 Hint: Think about the efficiency of active vs passive systems.

Challenge 2 Hard

If a transformer using ONAN is startled with increased loads, how might this affect its operational safety and what solutions could mitigate potential overheating?

💡 Hint: Reflect on how cooling systems adapt to changing loads.
