What is High Tension Power Line?
A high-tension power line is a transmission or distribution line. The underground or overhead transmission line is the major part of the electrical power system. Those lines are used to transmit electrical power from one place to another place which are called transmission lines or high-tension power lines. High-tension power lines mean that the line carries very high voltage. The transmission line carries very high voltage and most of the time transmission line rushes near the residence. For this reason, most people ask the question does 500KV high tension power lines near homes safe? We will also discuss how long should be the distance of house from high tension power lines.
Does 500KV High Tension Power Lines Near Homes Safe?
Does high tension line near house safe? No, it is not 100% safe if the 200KV, 400KV, or 500KV high tension power lines go over your home. It is because; transmission line sag is increased due to hot weather and some factors. If transmission sag becomes high over the home point then that can have a risk for the house people due to the very high voltage. Sometimes it can cause a fire.
On the other hand, if such a high voltage line goes near the home then there is no more problem for it because the high voltage transmission tower becomes very tall. Also, rules should follow before constructing a house or before making a transmission design. However, if the transmission voltage becomes more than 50KV then people should build a house at least 10 feet away from the 50KV transmission pole. If the voltage becomes more than 132KV then you must build a house at least 15 to 20 feet away.
Safe Distance from High Tension Power Lines
We are human beings and human health is a good conductor of electricity if we touch the ground. For this reason, we should follow some distance from the high-tension and low-tension power lines. It is noted that there is no evidence that high tension transmission line can cause dangerous diseases or health risks.
It is noted that science is unable to find the negative impact of high-tension line voltage they did not find an authentic reason for the effects of high-tension power lines on humans. Whether high tension line voltage is safe or not but we must follow a safe distance. See our chart that we will try to follow and continue to maintain a safe distance to live from high-tension power lines.
Transmission Line Types Depending on Voltage
The transmission line is the major part of the electrical power system. A high-tension power line is also called a high-voltage overhead transmission line. A high-tension power line means that those lines carry a high voltage to transmit from one place to another which is called high tension power lines.
High tension wires or power lines deliver electric power over a long distance. It is noted that transmission voltage varies on the transmission distance. For this reason, there are three main types of transmission lines in the power systems we have given three main types of high tension power lines based on the transmission voltage. Let’s see the types of overhead transmission lines that is very necessary for us.
| Transmission line type | Transmission voltage range | Type of pylons | Ending point | Types of substation | Conductors per system | Type of conductors |
| Low voltage transmission line | 0 to 1000 volts | Wooden poles, concrete poles, lattice poles, etc. | Indoor substation | Indoor substation | 3 phase 4 wire system | Single phase line |
| Medium voltage transmission line | 1000 volts to 50000 volts | Wooden poles, concrete poles, lattice poles, and others. | Indoor substation poles | Indoor substation, pylon transformer | Three phases three-wire system | Single conductor |
| High voltage transmission line | 50000volts (50KV) to 200000 (200KV) | Lattice towers, steel towers, high insulated wooden poles | Outdoor substations, relay termination towers, or indoor substations | Outdoor substation but it can be an indoor substation (rare case) | Three phases three-wire system | Single circuit or double circuit sometimes triple circuit |
| Extra high voltage transmission line | Transmission voltage range of more than 200000 volts (200KV) | Steel tower, lattice tower | Outdoor substations, relay termination towers, or indoor substations | Outdoor substation but it can be an indoor substation (rare case) | Three phases three-wire system | Double circuit, triple circuit, or more but single rarely > 250 kV |
How is the High Tension Power Lines Voltage?
Voltage is generated at 11KV in most of the power plants. This voltage is stepped up to 132KV, 220KV, 400KV, 700 KV, or more based on the transmission line distance. This voltage is stepped down to the 33KV and sends it to the different secondary transmission substations. This 33KV is step down to the 11KV and that is also run near the locality and 11KV is step down to the 400V or 0.4KV for our use.
But what is the high voltage power line voltage? Basically, we consider the high-tension power line is more than 11KV. We have given a chart above and we have shown some creative and different things to understand easily. We have shown there the high tension electric pole limit for high voltage limit, high tension wire for voltage, and others. So, see the above chart to get your answer.
What are High Tension and Low Tension Power Lines?
High-tension power lines are typically used to transmit power from a remote power plant to a long-distance substation, where the electricity is stepped down for distribution. Low-tension lines are used for the distribution of power in urban areas. High tension is usually higher than 11 kilovolts, and low tension is usually lower than 11 kilovolts.
Is 26V AC More Dangerous Than 100V DC?
No, 26V AC is not more dangerous than 100V DC. The danger of an electric shock depends on a number of factors, such as voltage, current, and the duration of the electric shock. Basically, higher voltages are more dangerous, but the current is also important. A small current that flows for a long time. It can be just as dangerous as a large current that flows for a short time.
In the case of 26V AC and 100V DC, the voltage is not high enough to be immediately dangerous. However, if you were to touch either of these voltages, it could cause a painful shock. The duration of the shock would also be a factor. If you touched the 26V AC for a long time, it could potentially cause more damage than the 100V DC.
Ultimately, the best way to avoid electric shock in all conditions. So, avoid touching electrical wires or appliances that are not properly insulated.
Final Thought
The transmission line is an important part that carries power for long and small distances. The power line can carry different systems with various voltages. Sometimes power lines become harmful if it goes near the house. We have discussed does 500KV high tension power lines near homes safe. We have never found any major issue with it but we should maintain distance from the power lines to avoid any undesired event.
