Question

if load on transformer is increased by 10% copper losses

Answer 1

Answer:

Supposing the increased load was at or less than the max allowable load, the three times greater current might dissipate nine times the earlier copper energy loss. If the rated load is much exceeded, then the magnetic element may well saturate of the current increase could be greater.

Answer 2

Load on transformer is increased by 10% copper losses as losses occur in the transformer's windings.

Explanation:

• The transformer is the heart of any electrical system.
• Whether it is a distribution substation or a receiving station, it is the most expensive and critical asset under consideration.
• The second component of loss is known as copper or load loss because these losses occur in the transformer's windings (I2R loss).
• Copper loss is caused by the resistance of the transformer's winding materials and varies with load.
