Description
A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors or the transformer's coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer's core, and thus a varying magnetic field through the secondary winding. This varying magnetic field induces a varying electromotive force (EMF) or "voltage" in the secondary winding. If a load is connected to the secondary, an electric current will flow in the secondary winding and electrical energy will be transferred from the primary circuit through the transformer to the load. In an ideal transformer, the induced voltage in the secondary winding is in proportion to the primary voltage, and is given by the ratio of the number of turns in the secondary to the number of turns in the primary. Usually the transformers those installed in the substation shall be called power transformer having minimum rated voltage 69 kV and the ransformers those installed at the poles, pad-mounted, in the high rise buildings and small factories are called distribution transformer having maximum rated voltage 33 kV.
