Introduction to Transformer Notes PDF Notes

Transformers are electrical devices that are passive in nature, and transfer electrical energy via the process of electromagnetic induction, from one circuit to another. They are capable of increasing voltage (step-up) and decreasing voltage (step-down) levels to allow for better transfer and distribution of electrical energy.

Transformers with their ability to step up and step down is critical in the electrical energy industry, by allowing for efficient distribution of energy, transmission, and electricity consumption. There are different types of transformers that are categorized based on working voltage range, medium core usage, winding arrangement, and Installation location.

What is a Transformer?

A transformer is an electrical device that, by the principles of electromagnetic induction, transfers electrical energy from one electric circuit to another, without changing the frequency. The energy transfer usually takes place with a change of voltage and current.
