Power transformers are used in residential, commercial, or industrial settings to regulate the amount of power needed for a specific application. Most people do not know when their homes or businesses need power transformers. Moreover, they are clueless about what to look for in a power transformer. Below is an article with everything you need to know about power transformers.
When Do You Need Power Transformers?
The primary role of power transformers is to increase or decrease electrical voltage. Power transformers are often used in the power distribution network to step up or set down the power voltage. For instance, power from the mains must be stepped down before it is distributed to homes and businesses. If not, home and commercial appliances with a low voltage rating could blow up when connected to power. Transformers increase the voltage of motors running x-ray machines. They also help balance the voltage in batteries and stabilisers.
Buying A Power Transformer
The factors below will influence the type of transformer to purchase:
When buying a power transformer, the underlying principle is that the equipment should be durable, safe, and functional. Therefore, conduct a comparative analysis of what the various transformer manufacturers have to offer. For instance, the transformer tank should be robust, corrosive, and leakproof. If you intend to use the transformer outdoors, it should have sufficient protection against weather elements such as rain. An enclosure is a must-have if you plan to place the transformer close to flammable materials.
You also need to establish the transformer's performance. For instance, what is its efficiency? Transformers with a low-efficiency rating will lose power. Moreover, the transformer's construction should comprise high-quality materials to prevent copper, eddy current, flux, and hysteresis losses.
Type of Transformer
There are different types of power transformers, each with a specific application. They include;
- Step-up power transformers convert low-voltage high-current power into high-voltage low-current power.
- Step-down power transformers have a contrasting operating mechanism. They change high-voltage low-current power into low-voltage high-current power.
- Isolation transformers protect electrical devices from power surges. Typically, they isolate the incoming load while simultaneously supplying an alternating current.
- Single-phase transformers have one pair of windings. They are suitable for small-scale applications such as homes and light industries. On the other hand, three-phase transformers are suited for heavy applications such as industries and urban power distribution grids.
The above guide should help you determine the need for a transformer and buy a transformer. Always work with professionals to ensure the transformer serves your current and future needs. Look into power transformers for more information.
