Lightning is created by the buildup and discharge of electrical energy in the atmosphere during a thunderstorm. Inside a storm cloud, strong air currents cause collisions between ice particles, which transfer electric charges—lighter particles become positively charged and move to the top of the cloud, while heavier, negatively charged particles gather at the bottom. This separation of charge creates a strong electric field. When the electric field becomes intense enough, it overcomes the insulating properties of the air, and a channel of negative charge, called a downward leader, begins moving toward the ground. As it nears the surface, positively charged upward leaders rise from tall objects or the ground to meet it. When they connect, a powerful discharge of electricity occurs—this is the lightning flash. The rapid heating of air around the lightning channel causes it to expand explosively, producing thunder (Lightning).

After downward leader overcomes the insulating property of air it travels to a place where it can neutralize its energy. This could be within the cloud itself, between one or more clouds or it could be heading to earth (ground). While lightning energy is moving, it searches for a place where it has high intensity of positive charge. Places like high rise buildings, trees (Coconut), open areas with respectively high altitude. If lightning downward leader meets one of above places it will create large damage to that particular place if it is not safe guarded with proper lightning protection.

Lightning protection system comes in between this downward leader and intercepts the lightning current. With the use of its system it guides this energy to the ground via a safe path.

Yes and its a must. Lightning strikes can cause fires, power surges, structural damage, and harm to people or equipment. Homes, commercial buildings, and sensitive infrastructure benefit greatly from having a properly installed system.

There are two standards which are mainly adhered worldwide. BS/ IEC 62305 (British or International Standard) NFC 17-102 (French Standard) In Sri Lanka SLS 1472 is used and it is derived mainly from BS 62305 standard.

No it doesn’t. This is a myth. Lightning protection protect the respective entity while having hypothetical covering radius. To simply this a mosquito net can be taken into consideration. Protection person is the interested entity and mosquito net works protects person with its covering area. Note : This is just simple explanation. The design and study is more complicate.

This has to be done by electrical design engineer which has speciality in Lightning and surge protection system.

This could possibly be due to surge currents coming through your power line. Surge Protection device should be installed to prevent these incidents.

No. Absolutely not. This also a myth. Trip switch is used to detect difference of incoming and outgoing currents from electrical system. Trip switch working time range is in mili seconds. Surge currents comes in micro seconds. Before trip switch acts on surge currents it already enters the electrical system and does its damage.

Product guarantee is only provided for surge protection systems and lightning protection systems. Natural disasters can only be minimised because the scale of disaster can always change. Therefore warranty will not be provided. Insurance should always accompanied with system.
