5. Factors 5.1. Factors Influencing Heat ProductionLosses are the thermal sources of the transformer hot spot temperature. In large power transformers, the losses caused by leakage magnetic fields account for up to 30–40% of the total losses. The leakage magnetic field will cause eddy currents in structural parts, such as the pulling plate and the clamp, resulting in local overheating of the structural parts.

Formative assessment can be used by learning designers to evaluate a learners' comprehension, learning needs, and learning progress during a lesson, unit, or course. The general goal of a formative assessment is to collect detailed information that can be used to improve instruction and learning while learning is happening.
