Electric Transformer Types
When it comes to transformers, you have single phase and three phase transformers. From there, within each one, there are various types of transformers such as step-up transformers, oil filled transformers, dry transformers, padmount transformers. Padmount transformers are easily distinguishable from other transformers as they are ground-mounted units, typically encased in tamper-proof, locked cabinets. Pole-mount transformers are elevated on utility poles, primarily used to step down distribution voltage to a usable level for homes and small businesses. Below are the most popular types of transformers that the advanced search above will help you find and buy.

Electric Transformer FAQs
A 3-phase transformer is designed to operate on a three-phase power system, which means it can handle three alternating currents (AC) that are phase-separated by one-third of a cycle, or 120 degrees electrical. This design makes 3-phase transformers highly efficient for distributing large amounts of electrical power over long distances and especially suitable for powering large motors and heavy machinery in industrial and commercial settings.
A single-phase transformer operates on a single-phase power system, which involves only a single AC voltage cycle. These transformers are typically used in residential areas or for light commercial applications where the power demands are relatively low. Single-phase transformers are simpler in design and are used to step down or step up voltages for household appliances, lighting, and smaller commercial units.
Choosing between a used or new transformer depends on factors like budget, warranty, immediate availability, and specific requirements. New transformers come with the latest technology and full manufacturer warranties but at a higher cost. Used transformers can be more budget-friendly and available for quicker delivery but might carry risks regarding their condition and lifespan. It’s crucial to assess the reliability of the supplier and the transformer’s condition, including any refurbishments or certifications, to ensure it meets your operational needs. Surplus Record has some of the best transformer dealers in the world that all offer certificates with their transformers showing that they were fully tested and ready to be put in service.
Check if the primary and secondary voltage specs align with your electrical system or machines. Dive into the the load and capacity requirements to find a fit that matches the power demand you will need. Also, look closely at the insulation and cooling systems; they play a crucial role in keeping things running smoothly. These are the key points to to pay attention to, ensuring that the transformer is a solid match for your shop’s voltage and workload requirements.
Keep an eye out for irregularities such as overheating, unusual noises, or oil leaks. These indicators may suggest internal problems or insulation issues. Fluctuations in voltage, frequent tripping, or electrical surges can also signal potential transformer issues. Regular inspections, temperature monitoring, and thorough testing help in detecting problems early on, ensuring the reliability and longevity of the transformer.
In machine shops, the most popular transformers include isolation transformers, which protect equipment from electrical noise and provide safety; step-down transformers, used to reduce voltage for machinery operation; and control transformers, designed to supply voltage to control devices within machines. These transformers are essential for ensuring the safe and efficient operation of various machine shop equipment, providing precise voltage regulation and isolation from potential electrical hazards.
Transformers work by transferring electrical energy between two or more circuits through electromagnetic induction. A primary coil receives alternating current (AC), creating a magnetic field. This field induces a voltage in a secondary coil, with the voltage change determined by the ratio of turns between the coils. If the secondary coil has more turns, the voltage increases (step-up transformer); fewer turns decrease the voltage (step-down transformer). This process allows for efficient transmission of electrical power at different voltage levels without changing the total electrical energy.
