Multiple Choice

The X2 secondary bushing is by industry standards the ____ bushing.

In transformer secondary bushings, the labeling plan uses specific terminals for each function: the three phase terminals and a neutral point. The X2 designation on the secondary side is assigned to the neutral connection. This neutral bushing serves as the reference point for the winding and is typically grounded, providing a stable return path for single-phase connections and protection schemes. The other bushing designations would correspond to the phase terminals or other functions, not the neutral. So, the X2 secondary bushing being the neutral bushing aligns with how the secondary winding’s neutral is brought out and identified.
