In an additive polarity transformer, the x1 bushing is located on which side?

Explanation:
Understanding polarity markings on a transformer is key. For additive polarity, the secondary terminal that shares the same instantaneous polarity as the primary is designated as X1. This terminal is physically placed on the right-hand side when you view the transformer in its standard orientation. Putting X1 on the right ensures that, when the primary and secondary are connected in the same-phase arrangement, their voltages add together in the expected way. That’s why the X1 bushing is on the right side. The other positions don’t align with this standard connection pattern for additive polarity.
