Question

a 500 kva single-phase transformer has 90% efficiency at both half-load and full-load at unity power factor. what will the iron loss be?

Answer 1

Hence, the reading of wattmeter W, gives the .... at which the copper loss becomes equal to iron loss. .... Example 2.12 A 300 KVA transformer has 95% efficiency at full load 0.8 power ...

Answer 2

ANSWER

a 500 kva single-phase transformer has 90% efficiency at both half-load and full-load at unity power factor. what will the iron loss be: 18.55 KW
