Modern life is dependent on electrical electricity for everything. From offices and households to streets and stores, all rely on electrical systems to function. We are getting a direct electricity supply at our place, but how much do we know about the transmission and distribution of electricity?
Let’s comprehend the innovations and what the future holds for transmission and distribution.
What is the Transmission and Distribution of Electricity?
Transmission and distribution of electricity refer to the different stages of transferring electricity over poles and wires from the source to a home or a business. However, the transmission and distribution of electricity are not the same. The difference lies in the voltage level at which electricity moves at each stage.
Electricity generates from various sources such as wind, fuel, and coal. Once it is generated from the source, the electrical wiring system carries electricity to homes, streets, offices, and buildings. These lines of wires are found overhead or in the ground, and together, transmission and distribution lines make up the electrical grid.
Let’s break this down a little for further understanding:
Transmission
Transmission is known as the “interstate highway” of electricity delivery. It is an essential part of electricity delivery that moves bulk electricity from the generation zones over long distances to substations closer to areas where electricity is required. Transmission lines are broader, taller poles and towers which carry many wires over long distances. Transmission lines move extensive amounts of electricity at high voltage levels. These voltage levels are too high to deliver directly to a home or business, so distribution comes into play.
Distribution
In the electricity grid, if the transmission is the interstate highway, then distribution is a street of a smaller city. Distribution is the final step of electricity delivery that supplies the electricity from the generation station to the consumer. Before transmitting the electricity to the distribution lines, the voltage is first reduced in the transmission line by transformers and then sent to the distribution lines. This electricity traveling through the distribution system has safe voltage and can be delivered directly to a home or office. Distribution lines are wires that are easily seen along streets, homes or offices, etc.
To put it simply, the transmission of electricity is at a higher voltage than distribution. Transmission lines are the combination of the huge electric towers and wires connected to them, while distribution lines are the ones that lead directly to homes and businesses.
How Innovations are Impacting the Electricity Transmission and Distribution?
The electricity industry remains a hotbed of innovation, with automation, intelligent processing, improving the performance of electricity distribution networks and the quality of distributed electricity, and the growing importance of technologies such as machine learning and artificial intelligence.
