Distribution Transformers- An Economical And Efficient Way To Avoid Energy Losses

127Distribution transformers are an electrical device which helps in converting high voltage electricity into lower voltage levels suitable for use in both homes and businesses. It has a straightforward function of stepping down the voltage level and providing isolation amid the primary and secondary. This is done via electromagnetic induction. Such transformers are found in every sector of the economy- industrial, commercial and residential. Today there are innumerable manufacturers providing an assorted range of distribution transformer to be utilized in diverse industries.

Broad Classification A distribution transformer is categorized into various types, each designed for a specific purpose. These include;

  • Oil cooled transformer
  • Dry type transformer
  • OCTC distribution transformer
  • OLTC distribution transformer

Configuration and Working Principle of Distribution Transformers A distribution transformer works on the law of electromagnetic induction. It includes two or above windings that aids in transferring alternating current from a particular circuit to another. The current rate remains unmoved while the voltage steps down. Its construction can be categorized into two-types namely shell type and core type. The coils in the former type are usually flat while the latter type has cylindrical coils and a rectangular core. A distribution transformer transfers energy amid circuits via a core that comprises high-permeability, low-loss silicon steel. The current in primary coils or windings create a magnetic discrepancy in the core of the distribution transformer which in turn aids in generating a magnetic force or field produced by an altering electric field, through the secondary winding of the transformer. This magnetic field produces an electromotive force in the secondary windings. This electromotive force is popularly known as voltage. An electric current passes via the secondary winding which transfers electrical energy to the electric circuit or load attached to the output terminal through the transformer.

 Uses and application

Distribution transformers are extensively utilized in assorted fields such as wind mill power transmissions, consumer and domestic transformers, electricity board and industrial purpose. Few of its common applications are;

  • Radar systems
  • Tool machines
  • Photocopying machines
  • Transmission lines
  • Telecommunications
  • Lighting plants
  • Safety alarm
  • Data processing equipment
  • Test measuring and control systems
  • Sensitive electrical/electronic equipment

The Focus Towards Eco-Friendly Environment

A distribution transformer has a huge impact on the overall efficiency, reliability and cost of a network. Thus, opting for energy-efficient distribution transformers that are optimized for loading conditions and local service, the maintenance policies of the network, the utility’s investment plan and a definite distribution network will provide ample benefits for both the utilities as well their customers. With climatic changes looming on the horizon has led to a higher interest to protect the environment against the greenhouse gas emissions. Now it has become a regulatory requirement to install a distribution transformer of high efficiency that have minimum energy losses, eventually resulting in lesser pollutants getting discharged into the environment.

Conclusion

A major advantage of a distribution transformer is its outstanding capability of surviving overloads and are tailor-made to cater to customer requirements. It is highly admired owing to its outstanding attributes such as high durability, wide operating voltage scope, trouble free service, minimum maintenance and low temperature rise. Distribution transformers are largely contributing in numerous industries in its wrestle against electricity fluctuation.
