When transformers are installed to meet a customer's voltage needs, what can they be configured to do?

Transformers are versatile devices primarily used to change the voltage levels in electrical systems. When configured for a specific installation, they can be designed to either increase (step up) or decrease (step down) the voltage based on the requirements of the customer.

In a step-up transformer, the primary winding has fewer turns than the secondary winding, resulting in a higher output voltage, which is essential when electricity needs to be transmitted over long distances with reduced losses. Conversely, step-down transformers have more turns in the primary winding, reducing the voltage to a level that can be safely used by customer equipment.

This adaptability allows transformers to serve a vital role in electrical distribution and ensures that the voltage supplied meets the specific operational needs of different loads. Therefore, the capacity of a transformer to either step up or step down voltage, depending on the situation, highlights its crucial function in delivering appropriate electrical power.
