What is Transformer?

Definition of Transformer in Construction

The electrical equipment that changes the voltage of the primary electrical power, normally from a high voltage to a lower, more usable voltage. The transformer will transform the power into whatever power requirements the electrical engineer designated, when designing the electrical systems of the project. The transformer can be located on a pole in the street, or more commonly, will sit on a concrete pad located on the project site. The transformer pad or in some instances, vault, is designed to accept the transformer either on top or within, and is designed to have primary and secondary conduit running in and out of the transformer. The secondary conductors will exit the transformer after the voltage is reduced, as needed, and transfer this electrical power to the secondary power that the construction project will use. A transformer is also the a piece of equipment that transforms alternating current to direct current for use with electrical controls, door hardware operation, or other electrical components requiring a different form of electrical power to operate. Transformers become hot due to their function, and are normally placed in areas that promote ventilation. Transformers are constantly being improved and new technology as well as synthetic materials are advancing, to improve the performance, lighten the weight, and decrease the heat produced from transformers.
