Power Transmission

Power Generation, Transmission and Distribution- A Quick Guide

Electric power is something without which we just cannot imagine our lives in the world of today that is run by technology. Power transmission is continuously functioning round the clock to keep the lamps lit across the globe.

Most of us, who do not really understand mechanics, have very vague ideas regarding the whole process of how we receive electricity in our houses. Here is a bite of knowledge for you guys on how it happens. There is a mechanism behind it. Let us all plunge into it and find out what happens.

Generation of Electric Power

Generation of electricity can be done in a lot of ways. But coal is used to generate most of the world’s electric power. Others like potential energy of water, solar energy, geothermal energy, wind energy and nuclear energy are harnessed to produce a sizeable portion of electricity. All these energies are used to boil water to produce steam that turns turbines. It is this mechanical energy that is converted into electrical energy. We then use this electric energy to run all our appliances.

Transmission of Electric Power

Power transmission is the transfer of energy in the form of electricity in large amounts from the stations that generate to electrical sub-stations. Now, it is from these sub stations that we are provided with electric power.

Most power transmission that happens is in the form of three phase alternating current. High voltage direct current is used for transmission over long distances because it requires high efficiency to traverse. Owing to cost factors, the overhead transmission is done. Overhead transmission systems rely totally on the blanket of air around them for insulation and hence their requirements to match the standards of safety are few in number.

Electric energy is a form of energy that, unfortunately, cannot be stored and must be generated as per the current requirements. This is why transmission poles and structures are an integral part of supplying electricity. Depending upon the voltage and distance of transmission, there are different forms of towers that are available for transmission.

Types of Transmission Poles

1. Single pole
2. Tower
3. Double circuit pole
4. H-Frame

Keeping in mind the requirements, a suitable tower is constructed at ample distance from the generation of power. Power generation, transmission and distribution keep happening continually concerning the need.

Distribution of Electric Power

This is the shipment of electric power from the sub stations to individual buildings. Large consumers like industries are given power directly from distribution voltages whereas most small scale consumers receive power from a transformer. Distribution is usually done at a low voltage level.

Components of Distribution Network

  • Electric substation
  • Primary distribution feeder
  • Transformer
  • Distributors
  • Service Mains
