Concept explainers

Single Phase Transformer

A single-phase transformer is a type of power transformer. It is an electrical device that accepts converts the single phase alternating power into single phase alternating power. In this power conversion the voltage is stepped up or down. If the voltage is stepped up, the current will be stepped down and if the voltage is stepped down, the current will be stepped up.

Question

i. When a transformer full of magnetic material is overloaded and heats up what would happen to the magnetic properties, and which law would the material be associated with.

ii. Mention six (6) examples of materials used for the design of

any type of insulation.
