Electric power transmission, regularly referred to as electricity distribution, practically means moving electricity from where it is produced to the consumers. Electricity is generated by the power plants and distributed to the substations. These substations are dispersed all throughout high population areas.
In North America there are 3 major grids that use high voltage lines. These actually supply electricity to the whole continent. What is interesting is that in the past, distribution and transmission lines all belonged to a single company. This is no longer the case as the electricity market enjoys a much higher freedom. There are numerous companies involved in electric power transmission. We now have separate companies that handle distribution or transmission. Transmission companies use technology like from Lindsey Manufacturing to build high voltage power lines. The distribution companies are only responsible in moving electricity from substations to the consumers.
Transmission Lines And High Voltage
As we look at differences noticed in the construction of the high voltage lines and the various transmission lines that are currently utilized, it is easy to notice that there are many different alternating current types. In most situations the network utilizes three-phase AC. However, it is common to notice one-phase AC in various electrification systems, like with railways. We then have submarine power cables that are utilized for really long distances. High-voltage lines are common on land, normally for distances that are higher than 400 miles.
High voltage is utilized in order to move energy around because this lowers lost energy quantities. High voltage line construction projects are going to go through overhead power lines since the underground power stations always involve far higher overall costs. At the same time, it does take a lot more manual label and advanced tools to build the underground transmission lines and power stations.
The basics associated with electric power transmission are not that hard to understand. However, those that are interested in a career in such an industry need to go above and beyond. They need to know everything about the different possibilities available. Then, they have to become familiar with major generation and distribution networks. Only after that finding a suitable job is possible.
It needs to be added that green energy production is gaining a lot of popularity at the moment. This is important because the electricity that is produced in most parts of the world comes from sources that are non-renewable. With many of the modern green energy production systems we do have access to simpler distribution systems. The best example of that is solar power since the user can actually have all that is needed installed on-premises. However, with major network implementations the high voltage distribution lines are still needed.
As an example, when a power plant is built and relies solely on wind turbine power generation, the electricity created still has to be moved to the consumer. In this case the high voltage lines are still the best way to transfer electricity and lowest possible losses are still in place.
