It is only necessary to connect the similarly marked high- and low-voltage terminals if the transformers have the same voltage ratio, the same percent impedance, and the same angular displacement.

Question

Quizplus · Accepted Answer

Connecting the similarly marked high- and low-voltage terminals is only necessary if the transformers have the same characteristics of voltage ratio, percent impedance, and angular displacement. Otherwise, it may result in incorrect phase shifts and damage to the transformers.
