Detailed Information On Lightning Protection

By Martha Allen


Dwelling structures are prone to a number of risks that can generate mayhem results. They are vulnerable to sparks generated by thunderstorms during rainy seasons. Therefore, the buildings should be installed with lightning protection systems. This is an innovative development that has been embraced in the structural engineering specialty. The systems are also used in launching space crafts to discharge the generated charges.

The LPS entails the use of latest conducting components. The exposed component that is found on the artic part of a structure is the air terminal rod which has a protrusion with a sphere head. They are used for lightning discharge. The rods usually connect to the conductor cables which convey the charge to the earth. The current conducts through the ground rods where they are buried deeper in the ground near the building or structure being protected.

The components are grouped into either external or internal protection system. They are all aimed at protecting the structure from potential fire, mechanical destruction and people from injury. The external components usually intercept the strikes through the air-terminals to discharge them to earth via the down-conductor system. Current distribution takes place on the ground via the earth-termination system.

Similarly, the internal components are usually designed to shield the structure from treacherous sparking that results as thunder strikes. It is achieved by launching a bond that ascertains that the separation distance is maintained between the LPS and other conductors housed by the structure being protected. The bonding is made effective by surging the conductors to create a breakable interconnection in the systems used.

In an unprotected building, the spark may opt to conduct via the available conducting elements inside the structure. These elements include mobile devices, electric wires, water and gas pipes. The spark may also utilize the building roof if it is steel-framed. Therefore, installing the systems does prevent the occurrence of lightning but it offers a better and safer path that channel the current to earth. The integrated components work together to convey the immense current away from the building.

The current generated from a thunderstorm spike is usually high to protect by use of in-house power supply equipment such the UPS and surge protectors. Thus, the best and most effective way to protect your electrical devices from such strikes is the by unplugging all power cables and telephone connections when a major thunderstorm strikes near your structure. In addition, you can also ensure such devices under a specific policy if you reside in thunder sensitive locations.

Nevertheless, the LPS installed in your structure do not hinder lightning from striking. They are principally used to create a better and safer path to discharge the current to the near ground. The process requires the use of the right components for it to be effective. It is also advisable to disconnect the devices from power sources in times of austere storms.

Thus, dwelling structures are required by the statutes to be installed with protection systems in order to protect human life and properties in such buildings. An unprotected structure is vulnerable to get stroked by thunderstorm charges which results in calamitous effects. Therefore, the systems should be given precedence when constructing buildings.
