Why does the low voltage winding of the transformer is placed near to core?

Low voltage winding is placed nearer to the core of the transformer. Because the amount of insulation required to isolate Low voltage from the core is less as compared to when you place High Voltage nearer to the core. The primary winding of the transformer is also called tertiary winding. There are many advantages of placing low voltage winding on the transformer is placed near to core.

Advantages low voltage winding on the transformer is placed near to core:

  • This type of arrangement will save the intermediate winding insulation 
  • It reduces the leakage fluxes. So the iron losses and copper losses will be reduced
  • Generally, copper is used for conducting material in transformers. So, the less amount of copper is required
  • The breakdown of insulation will be reduced
  • The resistance of the primary coil is less. So, the heat produced by the coil is reduced.

These advantages will increase the efficiency of the transformer. The losses are reduced and maintenance cost is reduced.
