- Example 32 64 A 25 Kva 1 Phase Transformer 2 200 Volts To 220 Volts Has A Primary Resistance Of 1 0 2 And A Secondar 1 (32.36 KiB) Viewed 35 times
Example 32.64. A 25-KVA, 1-phase transformer, 2,200 volts to 220 volts, has a primary resistance of 1.0 2 and a secondary resistance of 0.01 1. Find the equivalent secondary resistance and the full-load efficiency at 0.8 p.f. if the iron loss of the transformer is 80% of the full-load Cu loss. (Elect. Technology, Utkal Univ. 1998)
