Introduction to Electrical Distribution System

Electrical Distribution System or Electric Power Distribution System is the process of electricity distribution from the main station of power generation to the final consumers. This process involves a lot of electrical equipment that smoothens the process of transmission of electricity from the power generation station to the consumer. The types of equipment used in this process are distribution substations, primary distribution feeders, distribution transformers and secondary circuits. 

In the Process of Electric power distribution, First, the energy is delivered in bulk from the power source to the distribution substations. Then, in the distribution substation, various voltage regulating devices are used to reduce the voltage of electric current for the distribution to the local consumers.

The Electrical Distribution System generally consists of two distribution channels, i.e. Primary Distribution and Secondary Distribution. In Primary Distribution, the primary circuits carry the high voltage electric power to the distribution transformer located near the house of the consumer. Then, in the secondary distribution, the distribution transformer lowers the voltage to 120/240V, which is then transmitted to the household of the consumer through secondary circuits.

Frequently Asked Questions

  1. What is the Meaning of Primary Feeders?

Primary Feeders or Primary circuits are the distribution circuits that transmit the electricity from the substations to the local distribution transformers. Their arrangement can be made in three different ways, i.e. Radial, Loop and Network types. They may be arranged under the ground or over the ground.

  1. State the Factors affecting the Electrical Distribution System Planning.

The Factors affecting the electrical distribution system planning are as follows:-

  • Types of Primary Distribution System.
  • The voltage level at the customer point.
  • Types of secondary circuits used.
  • Size and location of the distribution transformer.
  • Loads at the primary distribution level.
  • Size and location of the distribution Substation.
  1. Can you give the Definition of Distribution transformer?

A Distribution Transformer is a piece of important electrical equipment that is used in the process of electricity distribution. It is basically an electrical isolation transformer that converts high-voltage to lower voltage levels in the transmission process of electricity. The main function of an electric distribution transformer is to step down the high electric voltage to low electric voltage for the use of home and other industrial appliances. Almost all the electricity that is transmitted from the power generation station passes through at least one distribution transformer before being consumed by the end-user.
