About Power Transformer


Power Transformer Definition:

A Power Transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors—the Power Transformer's coils. A varying current in the first or primary winding in Power Transformers create a varying magnetic flux in the Power Transformer's core and thus a varying magnetic field through the secondary winding of Power Transformers. This varying magnetic field induces a varying electromotive force (EMF), or "voltage", in the secondary winding. This effect is called mutual induction with reference to Power Transformers.

If a load is connected to the secondary winding, an electric current will flow in the secondary winding and electrical energy will be transferred from the primary circuit through the Power Transformers to the load. In an ideal Power Transformer, the induced voltage in the secondary winding (Vs) is in proportion to the primary voltage (Vp), and is given by the ratio of the number of turns in the secondary (Ns) to the number of turns in the primary (Np) as follows:
