What are High Tension and Low Tension Power Lines? So, see the above chart to get your answer. We have shown there the high tension electric pole limit for high voltage limit, high tension wire for voltage, and others. We have given a chart above and we have shown some creative and different things to understand easily. 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.īut what is the high voltage power line voltage? Basically, we consider the high-tension power line is more than 11KV. This voltage is stepped down to the 33KV and sends it to the different secondary transmission substations. This voltage is stepped up to 132KV, 220KV, 400KV, 700 KV, or more based on the transmission line distance. Voltage is generated at 11KV in most of the power plants. How is the High Tension Power Lines Voltage? Transmission voltage range of more than 200000 volts (200KV)ĭouble circuit, triple circuit, or more but single rarely > 250 kV Single circuit or double circuit sometimes triple circuit Outdoor substation but it can be an indoor substation (rare case) Outdoor substations, relay termination towers, or indoor substations Lattice towers, steel towers, high insulated wooden poles Wooden poles, concrete poles, lattice poles, and others. Wooden poles, concrete poles, lattice poles, etc. Let’s see the types of overhead transmission lines that is very necessary for us. For this reason, there are three main types of transmission linesin the power systems we have given three main types of high tension power lines based on the transmission voltage. It is noted that transmission voltage varies on the transmission distance. High tension wires or power lines deliver electric power over a long distance. 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. A high-tension power line is also called a high-voltage overhead transmission line. The transmission line is the major part of the electrical power system. Transmission Line Types Depending on Voltage See our chart that we will try to follow and continue to maintain a safe distance to live from high-tension power lines. Whether high tension line voltage is safe or not but we must follow a safe distance. 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. It is noted that there is no evidence that high tension transmission line can cause dangerous diseases or health risks. For this reason, we should follow some distance from the high-tension and low-tension power lines. We are human beings and human health is a good conductor of electricity if we touch the ground. Safe Distance from High Tension Power Lines If the voltage becomes more than 132KV then you must build a house at least 15 to 20 feet away. 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. Also, rules should follow before constructing a house or before making a transmission design. 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. 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. It is because transmission line sag is increased due to hot weather and some factors. Does 500KV High Tension Power Lines Near Homes Safe?ĭoes 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. 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. The transmission line carries very high voltage and most of the time transmission line rushes near the residence. High-tension power lines mean that the line carries very high voltage. Those lines are used to transmit electrical power from one place to another place which are called transmission lines or high-tension power lines. The underground or overhead transmission line is the major part of the electrical power system. A high-tension power line is a transmission or distribution line.
