Question
Mention two main sources of power loss in real transformers.
Solution
Two causes of energy loss in a transformer are:
- Heat loss due to copper: It is the loss of heat energy over the resistance of the copper winding in the primary and secondary coils.
- Hysteresis loss: The loss caused by the heating of the core as a result of its repetitive magnetization and demagnetization cycles when an alternating emf is applied across the primary coil.

A group of students while coming from the school noticed a box marked "Danger H.T. 2200 V" at a substation in the main street. They did not understand the utility of a such a high voltage, while they argued, the supply was only 220 V. They asked their teacher this question the next day. The teacher thought it to be an important question and therefore explained to the whole class.
