What does the type of connection on the low side of a transformer depend on?

The type of connection on the low side of a transformer is primarily influenced by the consumer's voltage rating. This rating dictates what voltage levels the connected equipment or load is designed to operate at, ensuring proper functionality and safety.

When selecting a transformer, the output voltage must match the requirements of the devices it will serve. Different types of connections, such as wye (star) or delta configurations, can provide various voltage levels based on the specific needs of the consumer.

While other factors, such as the power supply type, transformer size, and safety rating, can play roles in the overall design and application of the transformer system, they do not determine the specific connection type on the low side as directly as the voltage rating provided by the consumer's requirements.
