Basics of Current & Voltage Transformer

In this transformer basics tutorial, we will see that a transformer has no internal moving parts and is typically used when a voltage change is required to transfer energy from one circuit to another via electromagnetic induction.

One of the primary reasons we use alternating current voltages and currents in our homes and workplaces is that AC supplies can be easily generated at a convenient voltage, transformed (hence the name transformer), and distributed across the country using a national grid of pylons and cables over very long distances.

The reason for increasing the voltage is that higher distribution voltages imply lower currents for the same power, and thus lower I2*R losses along the networked grid of cables. These higher AC transmission voltages and currents can then be reduced to a much lower, safer, and usable voltage level that can be used to supply electrical equipment in our homes and workplaces, all thanks to the Voltage Transformer's transformer basics.

The Voltage Transformer is more of an electrical component than an electronic component. A transformer is a simple static (or stationary) electro-magnetic passive electrical device that operates on the induction principle of Faraday's law.
