It’s not that the rod will always conduct the lightning, but it will do much better than the structure. If there is a strong electric field, this tall rod will send positive steamers to disperse the electric field. Make sure that the rod is taller than the building or structure. If you want to protect an open structure, you need to take a very tall lightning rod. Image: lightning rod against a cloud dark sky Typical Residential Lightning Protection System Even if it is not a direct strike, the conductors will pick the current. As a result, it will get a jump that diverts the strike to the ground safely. If the strike occurs near a lightning protection system, it will offer a low-resistance path. Whenever lightning strikes, it always looks for the lowest resistance path. The “jumping” occurs due to the difference in strike target voltage and the earth voltage. Being a good conductor, rods give a safe path to the ground without causing any lightning damage. If lightning strikes any surface with poor conductivity, it can cause physical damage to that surface. In addition to this, it also prevents the failure of internal systems. The lightning protection system prevents structural damage due to a voltage spike. These rods provide a safe, low-resistance, and alternate path to lightning’s high voltage electric currents. Generally, people believe that lightning rods attract lightning. Whatever is the form, a lightning rod functions only if it has a connection to the earth. It is available in different forms like hollow, flat strips, rounded, solid, or pointed. Mostly, lightning rods are made up of copper and alloys. You can also name lightning rods as air terminals, strike termination devices, or finials.Ī lightning rod can be of any conductive material. As a result, the lightning goes into the ground without passing through the building. When lightning strikes the building, it will first strike the rod. The rod is generally 2cm-2.5cm in diameter. The rod connects to the ground with the help of a cable or wire. It helps to protect the building or any other structure from lightning strikes. You can mount this metal rod on any structure. Benjamin Franklin first developed these rods. Lightning rods, also known as lightning conductors, are rods made of metal. So, to offer protection against lightning, you can install lightning rods in-home or business structures and do a lightning rod test often to make sure of its function. Thus, it can cause a fire that may harm people and property. It will pass through the electrical wires and electronic devices that are plugged into your home or business. But what if lightning strikes these buildings? When lightning strikes a building, it travels through these buildings to find a path to the ground. To protect yourself from lightning, you generally move inside your home or business. Lightning flashes are common in bad weather with thunderstorms.
