You have a transformer with core losses of 60 W and full-load copper losses at 200 W. If the transformer is running at 75% load, what are the total losses?
💡 Hint: Calculate copper losses based on the load percentage, then add core losses.
Evaluate the impact of using a higher-grade anisotropic magnetic core material on reducing hysteresis losses.
💡 Hint: Think about how material properties affect loss characteristics.
