Lightning can cause complete destruction to structures and buildings that they strike because they carry thousands of ohms of current. The huge amount of current discharged when a strike occurs destroys buildings and plants. It can also injure and kill human beings and animals. To avoid these effects, protection systems have been designed for installation on buildings. The installation is done at the highest point on the building. The system them runs along the height of the structure all the way into the ground. This is worth knowing about Oilfield lightning protection.
Lightning protection systems look like metal rods that points upwards on buildings. A path with least resistance to flow of electric current is provided by these systems for the lightning to flow through. Protection systems work based on this principle. There are four main parts that make up a typical protection system. Each part performs a specific function. They include surge suppressor, copper air terminals, copper clad ground rod and copper cable.
The fact that copper offers the best electrical conductivity makes it an ideal metal to be used. However, other metals can also be used too. Other systems in fact can only be built using aluminum. The protrusions visible on the building where the system is installed are air terminals. When a strike occurs, the terminals discharge the current.
A cable connects the air terminals to ground rods. The cable runs to ground rods which are normally buried 10 feet deep in the ground. Existing ground of circuit box and plumbing is used to ground the system. A connection is made between the surge suppressor and the circuit breaker box. This is to allow it to cover the entire electric system. Individual appliances and electronics can also be protected from current surges by installing surge suppressors at each appliance.
Most companies do their best to ensure that the system is concealed and unnoticeable to people. The only noticeable part of the system is usually the air terminals that unavoidably have to protrude above the building. The copper cable tends to weather and change color from the conspicuous orange color to a dull patina.
All kinds of buildings and structures can be installed with these systems. Boats, businesses, farm buildings, aircraft, homes, water tanks, and trees are examples of structures installed with arresters. There are certain standards in place that govern the design and installation of these systems. The standards are set by three organizations in the US, that is, LPI, UL, and NFPA.
The work of arresters is to ensure that the current that comes from strikes find a safe path into the ground. The current will go through any conductor in their path if arresters are not present. Examples of conductors that provide a good path for the current include gas pipes, rooftops, water pipes, phone cables, and electrical lines. The current travels through one or multiple conductors.
A better grounded conductor in the house or surrounding structures can be sought by the current from the strike if it is available. This can result to fires as the current can ignite fuel on its way. Materials such as wood, gasoline and paper can be ignited easily. The huge current can cause serious electrical problems by vaporizing electrical wires too.
