Factors to Consider when Selecting an Electric Transformer
main image

An electric transformer is a device that transmits electrical energy across circuits. Different industries utilize them for various purposes.

They usually employ them to step up or down (step down) the voltage strength of an electric current. For example, lowering the voltage of a normal power circuit to run low-voltage devices or raising the voltage of an electric generator to deliver electric power over a long distance.

Purchasing an electric transformer is a significant choice that you should consider carefully. Before purchasing, you need to examine the specification of electrical transformer to guarantee that its functioning is optimized and efficient.

When choosing an electric transformer, there are numerous critical considerations to make.

Number of Phases

You need to determine the type of equipment before planning the kind of transformer. Single-phase transformers are typically used for modest domestic appliances. A three-phase transformer design is for large enterprises with a significant load. The manufacturer specifies the phase and kind of equipment in its brochure with which the transformer is compatible.

The Environment in Which The Electric Transformer Functions

The most important element to consider when choosing an electric transformer is the environment in which the gadget will operate. The transformer’s parameters will change depending on the environment in which you will use it.

Operate the electric transformer in an open area with regular exposure to weather factors. It should be fluid-filled or oil-cooled. That will protect the metallic windings from the risks of changing weather.

People install many electric transformers in the most varied and severe weather conditions. Dry-type electric transformers that operate in areas with salty air and high temperatures need corrosion-resistant paint coatings.

Power on the primary and secondary sides of the transformer always remains the same. KVA on the Primary Side = KVA on the secondary Side (Under Ideal Conditions, Ignoring Losses)

Electric transformers are often expensive and require some precautions to keep them in good working order. Exterior paint with strong corrosion resistance, oil and pressure level monitoring, hot-dipped galvanized radiators, temperature and pressure control trip and alarm features are among them.
