The low voltage secondary bushings on an overhead transformer are connected to which windings?

• A. Secondary windings
• B. Primary windings
• C. Ground
• D. Neutral

Answer: (A)

The main idea is that bushings on a transformer carry the connections for the winding that side of the transformer is serving. The low voltage side uses the secondary winding, so the low voltage bushings connect directly to the leads of that secondary winding. The primary winding is on the high voltage side and has its own set of bushings. Ground and neutral are safety or return paths in the system, not the direct connections of the low-voltage winding through its bushings. So the low voltage secondary bushings are connected to the secondary windings.
