Question

which construction technique is used to reduce copper loss in large transformers​

Answer 1

Answer:

Copper losses are due to the resistance of the wire in the primary and secondary windings and the current flowing through them. These losses can be reduced by using wire with large cross-sectional area in the manufacturing of the coils.
