![]() ![]() These transformers vary in size depending on the voltage requirements for commercial or residential use. It is then sent to local distribution power lines with various types of transformers. This power then travels to substations with step-down transformers where it is reduced to 13.8kV, 60Hz. This generated power goes directly to a step-up transformer at the power plant and is increased to transmission voltage levels to travel long-distances across transmission power lines at 138kV to 500kV, 60Hz. In order to transport this generated power output to local industry and the general public, it must be able to go long distances with minimal losses. These generators produce AC (Alternating Current) power at 12.47kV (15kV Voltage Class). The vast majority of electrical power is generated by local power plants using huge turbine-operated 3-phase generators fueled by fossil fuels such as coal or natural gas.

Each post should take the average reader no more than 15 to 30 minutes to read. Every topic posted will likely be important to most people in the electrical industry at every level. My goal is to summarize and condense potentially complex topics that are most important to Electricians as well as Electrical Engineers into a “take-away” format, and also share application-specific insight and experience. I’ve been an Electrical Engineer for 36 years, and really enjoy writing condensed technical articles about topics that can benefit others in the Electrical industry. My name is Jim Bernth, founder of Electrician’s Journal. If you have any of these structures crossing any part of your property (over the house, garden or fields etc.Welcome to. ![]() These wooden power lines are very common and account for a large proportion of current power line compensation cases in the UK. Their affordability makes them well suited to remote rural areas and towns and villages alike. They are easily recognisable thanks to their proximity to the ground and simple design. For this reason, they are designed to feed from the larger types of power line above and are often found running close to public footpaths, roads, and-of course-residential properties. ![]() 66kV and 33kV powerlines can be found on steel frames, often sharing similar designs with 132kv lines, and wooden poles.ģ3kV and 11kV lines are the smallest high voltage lines found in the UK, and are usually mounted on wooden poles. In the UK these are UK Power Networks, Scottish and Southern Energy, Western Power Distribution, Electricity North West, Northern Power Grid, SP Energy Networks and Northern Ireland Electricity.Īll smaller lines are owned by the DNO companies, including 66kV, 33kV, and 11kV lines. Most of these are owned by Distribution Network Operators, DNO’s for short. These power lines tend to be carried by much smaller lattice steel pylons or even wooden poles. These pylons can be huge eyesores for nearby property owners due to their sheer size and scale, and can also generate noticeable noise pollution.Ī 400kV National Grid power line on Cheshire farmland These are perhaps some of the most easily recognisable power lines, carried by the large, steel lattice pylons you will have seen scattered across the British countryside.Ĥ00kV and 275 kV power lines are very common transmission lines in Britain. Owned and run by the National Grid, these power lines are the largest operated in the UK. Below are some of the power lines around us today. Depending on whether you live in a rural area, a town, or a city, your property could be within metres of any one of these powerlines.īeing able to identify the different types of power lines in Britain as well as reading our other blog article here will help you gain an understanding of their function and, potentially, whether or not you are eligible for power line compensation. There are a range of different types of power lines out there, each with their own voltages, structural features, and purpose. ![]()
