Transformer Forces

What is Force

Force is the capacity to do work or cause physical change or even physical damage.

Force in Transformer

In transformer, forces are produced due to the interaction of the current and the magnetic flux density. The force can have any direction in transformer. There are two types of forces in transformer.

  • Radial Force
  • Axial Force

Radial Forces

The force that acts in the radial direction are said to be Radial forces. Radial forces are generated by the interaction of the current and the axial components of the leakage flux density. Radial forces tend to squeeze the inner winding and burst the outer winding. Radial forces in the transformer winding can be easily calculated uses the formula below:

Axial Forces

The force that acts in the axial direction are said to be Axial forces. Axial forces are generated by the interaction of the current and the radial components of the leakage flux density. Axial forces tend to bend the conductors in the axial direction. Axial forces in the transformer winding can be easily calculated uses the formula below:
