Overview

Transformers are electrical devices used to transfer electrical energy between two or more circuits through electromagnetic induction. They are essential in various applications, including power generation, transmission, and distribution, as they allow for the efficient change of voltage levels, ensuring the safe and effective delivery of electricity over long distances.

FAQ

What should I consider when buying a used transformer?

Consider the transformer's age, capacity, voltage rating, and overall condition. Check for maintenance records and any signs of wear or damage, such as oil leaks or rust.

How do I ensure the transformer is shipped safely to my location?

Use a reputable transport service that specializes in moving heavy electrical equipment. Ensure the transformer is properly secured, protected from moisture, and handled carefully during transit.

What is the maintenance schedule for a transformer?

Regular maintenance includes checking oil levels, inspecting for leaks, cleaning and inspecting bushings, and testing insulation resistance. Follow the manufacturer's guidelines for detailed maintenance intervals.
