Question: 2 a 2400240 v 50kva transformer has the core loss...

Question details

2. A 2400:240 V, 50kVA, transformer has the core loss of 186W and copper loss of 617W when it operates at full load condition. Now it is connected as an autotransformer in the following figure. It is assumed that 240V winding has enough insulation to withstand a voltage of 2640V a. Calculate the KVA rating as an autotransformer. (10%) b. Determine the efficiency of this autotransformer at a rated load and 0.8 power factor lagging. (15%) V 2400 V g
