Two single-phase transformers with the same kVA rating are connected in parallel. Their respective per unit values of resistance are 0.005 and 0.01 and the per unit values of reactance are 0.05 and 0.04. Together they supply a load and one of the transformers is fully loaded. State which one this is and calculate the proportion of its full load handled by the other one.
Explain how and when transformers can be connected in parallel. What are some of the risks when connecting transformers in parallel?
