Multiple Choice

The primary bushings on an overhead distribution transformer are labeled H1 & H2. If you are facing the transformer, which bushing is on the left?

When labeling high-voltage bushings on an overhead distribution transformer, the letters denote left-to-right positions from the viewpoint of someone facing the front of the unit. The bushing on the left side is designated H1, while the one on the right is H2. So, if you’re standing in front of the transformer looking at it, the bushing on your left is H1. That’s why the left-hand bushing is the correct choice. Top or bottom aren’t used for this labeling, since the designation is about left-right position from the front view.
