Challenge Problems
Push your limits with challenges.
Question 1
A transformer has core losses of 300 W. Its full-load copper losses are 600 W. How do these losses affect the overall efficiency when the transformer is operated at 60% of its capacity?
💡 Hint: Keep in mind how copper losses vary with load.
Question 2
In a practical application, a transformer has 150 W of core loss and 450 W of copper loss at full load. If it operates at varying loads, how would you find total losses accurately using open-circuit and short-circuit test data?
💡 Hint: Reflect on how the tests are structured to offer results.
