Q3. A 10-kVA distribution transformer has full-load efficiency at unity power factor of 95%, the copper and iron losses then being equal. Calculate its all-day efficiency if it is loaded throughout the 24 hours as follows:1- No load for 6 hours2- Quarter load for 6 hours 3- Half-load for 6 hours 4- Full load for 6 hours Assume load power factor of unity.
