Lightning Surge Protection??

       Lightning surge protection, lightning strike, surge arrestor, surge protection, lightning protection system, power surge protection are uncommon topics to Malaysians despite the fact that  Malaysia is the country with the third highest number of lightning strikes in the world. Lightning is considered the worst natural killer, causing at least 25,000 deaths worldwide and financial losses at approximately 5 billion dollars each year.

What is lightning surge??

       When electric charges are built up in thunderclouds to such level that could break atmospheric insulation, an electric discharge eventually occurs between these clouds or between the clouds and the ground. Electric current reaches 20-150 kA. According to an experiment done in Klang Valley. The average surge current magnitude of lightning strike is approximately 35-100kA.

An abnormally high voltage generated by direct lightning discharge applied to electric power cables or communication cables at that instance is called ʻdirect lightning surgeʼ. Correspondingly, such voltage induced by electrostatic or electromagnetic induction on those cables located close to the point where a direct lightning hits, is called ʻinduced lightning surgeʼ. Also, when lightning strikes a lightning rod and the ground potential rises, instrumentsʼ grounding potential becomes also high. This causes an abnormally great potential difference between the cables and the ground, which is called ʻlightning surge caused by increased ground potentialʼ.

Entry pathway of lightning surge

Due to the online application of modern electronic systems, there are multiple interfacing parts to the outside for an instrument. One of such interface parts is signal pathway and the other one is power pathway.

These cables pulled from the outside can be perfect entry pathways for the lightning surge.

The effects of induced surge on a connected device will be more severe when the connected cable is longer and the device is located closer to the place where the actual lightning strikes. Even lightning rods with minimal cable length do not always protect as they are hoped.Surge protector, or lightning arrestor installed in those  paths absorb and eliminate the high voltage impulse energy and protect the electric instrument from damage.

What damage is caused?

Lightning surge interrupts or affects the continuous flow of normal power can cause a transient overvoltage to be induced onto the mains supply to your electrical equipmentwhich can lead to serious damage to any equipments connected to surge pathways. Just look at your home appliances such as computer, LCD TV, hi-fi system, air conditioner, alarm system, CATV decoder, autodamaged autogate control panel and basically everything connected along the surged line.
