This is because the losses in a transformer are proportional to the square of the current. When the transformer is operating at near full-load, the current is lower than when it is operating at no-load or half-load. This means that the losses are also lower, and the efficiency is higher.<\/p>\n<p>When a transformer is operating at no-load, there is no current flowing through the secondary winding. This means that there is no power being transferred, and the efficiency is zero. When a transformer is operating at half-load, the current is flowing through the secondary winding, but it is not as high as when the transformer is operating at full-load. This means that the losses are higher than when the transformer is operating at no-load, but they are still lower than when the transformer is operating at full-load.<\/p>\n<p>When a transformer is operating at full-load, the current is flowing through the secondary winding at its maximum value. This means that the losses are at their maximum value, and the efficiency is at its minimum value.<\/p>\n<p>In conclusion, power transformers are generally designed to have maximum efficiency around near full-load. This is because the losses in a transformer are proportional to the square of the current.
