What Will Happen If Transformer In Parallel Connection Have Different Voltage Ratio? |
|
Answer» Two transformers in Parallel should have the same primary and secondary voltage RATINGS. Any ERROR in the voltage ratio would cause heavy circulating currents to FLOW between the transformers. This circulating current will RESULT in a corresponding imbalance in the primary currents, and result in overloading of one transformer. This circulating current will result in increased copper losses. Two transformers in Parallel should have the same primary and secondary voltage ratings.
