Example 32.80. Two 100-kW transformers each has a maximum efficiency of 98% but in one the maximum efficiency occurs at full-load while in the other, it occurs at half-load. Each transformer is on full-load for 4 hours, on half-load for 6 hours and on one-tenth load for 14 hours per day. Determine the all-day efficiency of each transformer. (Elect. Machines-I, Vikram Univ. 1988)
