A transformer is a device that is designed to transfer electrical energy between multiple circuits. Industrial transformers are used for a variety of applications in the automotive industry, oil and gas industry, chemical industry, and metal and mining. Purchasing an industrial transformer can be quite a large investment, so it is important for a company to purchase the right one. Consider the following things when you're in the market to buy an industrial transformer:
Number of Phases Needed
Transformers are available as either single phase or three phase. The type of transformer you will need will depend on the type of equipment that your company uses. Single phase transformers are suitable for small machinery, while three phase transformers are more commonly needed when a company uses heavy equipment.
Before you can purchase a transformer, you will need to know your voltage requirements. It is essential to know both the input voltage and the output voltage. The type of voltage that you will need depends on the power supply used and the type of equipment that will be hooked up to the transformer. You do not want to make guesses when it comes to your voltage requirements; if you are unsure, work with a transformer sales company to determine your exact needs.
Where the Transformer Will Be Placed
Transformers can be used indoors, outdoors, and in hazardous areas. It is important to consider the placement of a transformer prior to making a purchase. If you will be placing your transformer outdoors, you will need to look for one that is liquid-filled in order to protect the transformer winding from weather elements. Transformers that will be used in a hazardous area must be designed with specific features that meet local regulations.
Size and Space Requirements
Most transformers are built around standard core sizes, so you will need to determine what size transformer you need and how much space you have for the transformer. If you need a transformer for your company but have very little space to house it, it may be possible to have a custom designed industrial transformer fabricated for you.
The frequency of a transformer will be determined by the power supply that you use to power the transformer. If you are located in the United States but plan on using heavy equipment imported from other countries, you may need to purchase both a transformer and a frequency converter to ensure that your equipment is compatible with your transformer.
