A transformer is an electrical device that can convert a low voltage current to a high voltage current and a high voltage current to a low voltage current. Power generation plants and power distribution companies use transformers extensively. Without transformers, the conversion and distribution of electricity would not have been possible.
The power transformer mainly reduces power losses while transmitting a far distance from power plants to the distribution company. This website previously discusses the different parts of the transformer; now, the ‘Power Transformer Circuit Diagram’ will be discussed in this article.

What is Power Transformer?
The power transformer is an instrument used to enhance or decrease voltage from a low voltage of high current or high voltage of low current. Generally, this transformer’s size is big and weightful. Power generation plants and distribution centers use this type of giant transformer.
Where Power Transformers Are Used
This power transformer has to be used where the voltage has to be increased or decreased. Electricity producing plants and distribution companies use this transformer for the purposes. This transformer is used to reduce transmission loss. The equation of the transmission losses of the power transformers is P = I*I*R. Sub-center of the power distribution companies is used this power transformer.
Power Transformer Circuit Diagram
The power transformer is designed for high efficiency with 100% load, and it can work 24 hours in a row. This transformer’s winding is highly insulated. The power transformer circuit diagram is elementary to understand.
All of the transformers work on Faraday’s electromagnetic induction law. All the principles of a transformer are built around this formula. We try to give an idea about the circuit diagram on the power transformer.
The transformer is heated a lot as a result of continuous running. Circuit diagrams are made so that it does not cause any damage, reduced work efficiency, or short circuit even in extreme heat.
Here is the transformer’s basic information given below:
- Primary windings turn number is Np
- Secondary windings turn number is Ns
- The primary current is Ip
- Secondary current is Is
- The primary voltage is Vp
- Secondary voltage is Vs
Step-down transformers are made by increasing the number of turns of the main coil by reducing the number of turns of the secondary coil. Step-up transformers are made by doing the exact opposite.
