How can we protect our towers from lightning?
The lightning rod must always be located at least two metres above any other object within its protection radius and therefore must be above any antenna. The antenna poles must be attached to the lightning protection system, which is usually achieved via the metal structure.
Does Network tower attract lightning?
“The answer to your first question is yes, lightning is a threat to strike communication towers and can do great damage if the tower is not protected appropriately.
What happens when lightning hits a cell tower?
When lightning strikes a cell tower, the large amount of lightning current injected and dissipated in the earth near the tower can cause severe earth potential rise (EPR). It can drastically increase voltage gradients in the earth, even finding its way through the neutral and the earth electrodes into nearby dwellings.
Do radio towers get struck by lightning?
Communication towers are tall structures, which makes them prone to lightning strikes. In fact, the taller the tower, the more likely it is to get struck by lightning.
What is the use of lightning arrester?
A lightning arrester (alternative spelling lightning arrestor) (also called lightning Isolator) is a device used on electric power transmission and telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightning.
How does lightning protection system work?
Lightning protection systems and strike termination devices (rods) simply intercept a lightning strike and provide a safe and effective path that takes lightning’s harmful electricity to ground.
Does mobile tower attract thunder?
Cell phone use distracts the individual so that they are not paying attention to the sound of thunder (a primary warning sign), nor to the truck that is approaching to run them down, etc, so not using a cell phone is a good recommendation, but NOT because it ‘attracts’ lightning.
Do antennas attract lightning?
TV Antennas are a good conductor of electricity, so they could certainly attract lightning. During a thunderstorm, anything conductive that is not grounded will gather a static charge; as this charge accumulates, it naturally attracts lightning.
How does lightning affect communication?
A thunderstorm and its lightning discharges create disturbances in the ionosphere that perturb and distort radio signals and impact communications with orbiting satellites.
What is difference between surge arrester and lightning arrester?
Surge arrester protects the installation from inside while lightning arrester protects the equipment from outside. Surge arrester protects the system from lightning, switching, electrical faults, and other transients voltage and surges while lightning arrester is mainly used for lightning strikes and associated surges.
Is lightning arrester necessary?
Most residential homes don’t need lightning protection. However, if you have the following conditions then a lightning rod and lightning protection makes sense: You live in an area with a high frequency of lightning strikes. The home is tall.
What are the 3 parts of a lightning protection system for a building?
A lightning protection system consists of the following five parts: air terminals (lightning rods), conductors, ground connections (electrodes), bonding, and lightning arrestors.
