- Occur same as in distribution line and are lesser in quantity as compared to core losses.
- Copper losses are nothing but dissipated heat by the current in primary as well as secondary winding which can be found out by the current square relation with resistance.
- Any factor affecting current and winding resistance obviously affects copper loss in the transformer.
- Increase in real or reactive loading causes more flow of current hence more copper losses.
- Resistances of winding depends upon length and size of winding conductors.
- This has an important contribution in the amount of copper loss in the transformer.
- Change in temperature of the winding causes changes in resistivity of the winding conductors hence overall resistance hence copper losses of the transformer.
