43. A 250KVA, 2000/400V, single phase transformer achieved its variable loss equal to its fixed loss at 80% of its full load at its lagging pf showing the value of 0.76. Calculate the efficiency of the transformer at 0.8pf leading at one half of its full load. Also, calculate load dependent losses , iron losses at full load and total associated losses when connected to the system
