Step Down Transformer Construction

Step Down Transformer Construction

Transformer plays an important role in electricity by changing the voltage, current, and other things. It can also use for measuring the high voltage current. The power generating and distribution centers can’t work or optimize electricity without a transformer.

There are many kinds of transformers that are designed for various purposes. The step-down transformer is designed to decrease the voltage. This blog will give the information on step-down transformer construction below.

Transformers are constructed by considering windings. Single phage and the three phages transformers construction method is the same. The windings are not connected with any physical wires.

They pass electricity through the medium of IMF (electromagnetic force). The transformer works in the principle of Np/Ns=Vp/Vs=Is/Ip. In a step-down transformer, the secondary windings are always less than the primary windings. The functional equation is Ns<Np.

The main raw materials of the laminated iron core. The windings are wounded on it and create a magnetic core. The whole of the system is covered with an oil-filled tank. And some other parts joint with the tank. These parts names are given below:

  • Bushing
  • Cooling tubes
  • Cooling fans
  • Insulating oil
  • Explosion vent
  • Buchholz relay
  • Oil conservator
  • Breather
  • Radiator

Although a step-down transformer is heavy, it has a number of wheels for easy moving. The whole of the transformer installed a local place for avoiding unwanted happens like electrical shocks and other reasons.
