How Electricity reaches our homes – different ways of distribution


We all rely on electrical energy in our day by day lives to preserve going, whether or not it’s turning on our computer systems for work, observing television, grabbing a sandwich from the refrigerator, the use of an ATM, or charging our telephone phones. It all looks very easy and easy. But have we ever idea about what makes up electrical energy and the place does it come from? This publish will supply talk about how Electricity reaches our homes, a number of places/ phases/ networks it takes and the challenges confronted through Power Grid Stations in handing over it to us.

How Electricity Reaches Our Homes?

The Electricity reaches our residences by means of passing via following places/ phases/ networks:

  • Power Grid Station
  • Transmitting Substation
  • Transmission Network
  • Receiver Substation
  • Distribution Network
  • Consumer (Home/ Office)


  1. Power Grid Station

It begins existence in a grid station, which is a massive plant placed commonly close to strength producing sources such as hydroelectricity dams, wind or solar farms and herbal fuel plants. Power flowers use gasoline as sources of power from wind, coal, solar or even nuclear energy.

This power is then transformed into electrical energy the usage of gear consisting of boiler, furnace, turbine, cooling tower and generators. This electrical energy is then transformed into excessive voltage and transferred to massive substations with the assist of overhead lines. This voltage can be as excessive as 25000 Volts or more.

  1. Substation

Substations are an necessary section of the electrical energy transmission. Usually positioned close to electricity grid stations, they expand the voltage even further, as a consequence permitting it to be transmitted to longer distances whilst conserving power. This is performed with the assist of Step Up transformers which can amplify the voltage.

When electrical energy passes via the first substation transformer, it subsequent goes to transmission network.

Why High Voltage Transmission between Substations?

  1. Transmission Network

A transmission community helps cross electrical energy from strength substations to a distribution network. It enables shipping of electrical energy to give up customers such as houses, workplaces and business areas. The voltage is nonetheless very excessive at this stage due to the fact electrical energy has to cowl lengthy distances earlier than it reaches the stop user.

Transmission community is made of overhead strains on metallic pylon, or, strains buried underground. These traces are insulated to preserve them protected from giving electric powered shock in case they come in contact with a human, seeing that they elevate ultra-high voltages.

  1. Receiver Substation

Again, with the assist of Step Down Transformer, electrical energy voltage is decreased to a secure and preferred level. Voltage reduce is required at some stage in distribution to make it secure and less effective earlier than electrical energy enters households. At this stage, electrical energy leaves the transmission community and reaches the distribution network.

Depending upon the place and usage, substation kind and voltage can differ. For instance, industrial areas may also require the voltage to be decreased to round 33,000 volts whereas city areas with small factories may also require voltage between 11,000 to 33,000 volts. Transformers distributing electrical energy to homes and structures on the different hand will supply voltage as low as 230 volts.

  1. Distribution Network

From substation transformer, the electrical energy enters the distribution community traces to attain its closing destination. These strength traces should be underground or overhead in special areas. Once it reaches a neighborhood, it passes via any other small road transformer to similarly decrease the voltage – therefore making sure its security of use.

  1. Consumer (Home/ Office)

As a ultimate step, it passes via provider drop and your meter information the electrical energy used through you. It receives divided into circuits for all areas of the house/ places of work at the switchboard, and ultimately transmits via the wires interior your partitions to energy switches. Here is the place you effortlessly function all your electrical home equipment and lights.

Challenges confronted via Power Grid Stations

The essential challenges confronted with the aid of Power Grid Stations are as follows:

  • The energy grids are vital for power era to make sure a protected stability of provide and demand of electricity. But in places the place transmission and distribution networks have already served their beneficial life, they want to be renewed or replaced. This requirement is necessary to preserve the reliability and continuity of electrical device and additionally to create hyperlink with renewable strength sources as they emerge as more and more popular.
  • Setting up of New Transmission strains for enlargement of network.
  • Security from Cyber and Physical assaults.
  • Uncertainty in State legal guidelines about paying costs.
  • Finding a worthwhile method between charges worried and customer price estimation.
  • Continuity of Fuel resources.
