What is the primary function of the secondary bushings in a transformer?

The primary function of the secondary bushings in a transformer is to connect to load circuits. These bushings are essentially conductive terminals that provide a path for the electrical energy to be transferred from the transformer to the external load. When a transformer operates, the primary side receives the input voltage, and the secondary side delivers the transformed voltage to the connected load. Therefore, secondary bushings play a crucial role in establishing this connection, ensuring that power is delivered effectively to the devices or systems that require it.

While grounding, insulation, and wattage are important aspects of transformer operation, they pertain to different functions or components within the transformer system. Grounding relates to safety and fault management, insulation helps maintain proper operational voltage levels, and wattage is a measure of electrical power rather than a direct function of the bushings themselves.
