Question

how to determine copper loss in a transformer in which test​

Answer 1

Hey Mate!!

Copper loss in the transformer is measured by the short-circuit test of transformer. For measuring copper loss first we short-circuit the transformer low voltage side. After the short circuit of LVS, a small voltage is applied on H.V side till rated current flow in L.V side.

The copper losses are calculated from P = I^2. R. So assuming R remains constant, the copper loss reduction is the square of the load reduction. For example, is the load is 71% of full load, copper losses reduce to 50% of full load copper losses.
