1. How does the load-sharing of the two transformers appear when the load changes during parallel operation of the transformer? 2. For what reason is the load current IL [A] always the same as the sum of current I1 and I2 flowing to each transformer, If not, for what reason? 3. What will be the load-sharing ratio between parallel operation of transformers with the same conditions and parallel operation of transformers with different rated capacities? 4. What happens when the ratio of each resistance and leakage reactance is not the same? 5. If U.V. is not shown on the primary and secondary windings of the transformer, what procedures and methods should be used to make parallel connections?
