Which Type of Transformer is Used for Distribution Purpose

Transformers are essential components of the power distribution system. They are used to convert the high voltage electrical energy produced in the power generation plants into low voltage usable form, which is then supplied to the consumers. There are different types of transformers used for different purposes, and when it comes to the distribution of power, the most common ones are distribution transformers.

Distribution transformers are used to step down the voltage level of the electricity from the transmission level to the distribution level. They have a rated capacity of up to 2500 kVA and are typically installed near the load centers or on the poles. They are categorized into two types, i.e., pole-mounted transformers and ground-mounted transformers.

Pole-mounted transformers are the type of distribution transformers that are installed on the poles, either single-phase or three-phase. These transformers are lightweight, compact, and easy to install, making them ideal for residential areas. They are typically used for low voltage electricity distribution, and their capacity ranges from 2.5 kVA to 25 kVA.

Ground-mounted transformers, on the other hand, are the type of distribution transformers that are installed on a concrete platform or at the base of a pole. They are used mainly for industrial or commercial areas and provide high voltage electricity distribution. Their capacity ranges from 25 kVA to 2500 kVA and is dependent on the requirements of the load centers.

The primary and secondary windings of the distribution transformer are made of copper or aluminum conductors, and the core is made of laminations of steel. The core plays a crucial role in reducing the losses and increasing the efficiency of the transformer.

In conclusion, distribution transformers are essential components of the power distribution system and are used for stepping down the voltage of electricity from the transmission level to the distribution level. The type of transformer used for distribution purposes is dependent on the load requirements and the location of the load centers. Pole-mounted transformers are ideal for residential areas, whereas ground-mounted transformers are used mainly for commercial and industrial areas.
