Centre for Lightning Protection
Arthur C Clarke Institute for Modern Technologies
Are You Affected by lightning?
Lightning is a probabilistic natural phenomenon which causes massive damages and losses to man, animals and infrastructure with its direct and indirect effects which can be minimized using adequate preventive protection methodologies such as utilization of Lightning and Surge protection systems and following safety precautions. Sri Lanka being a tropical country, experiences a high level of lightning activity which results in damages and losses to living beings and property every year, mainly due to lack of awareness, absence of regulations and adequate testing facilities in accordance with recognized national and international standards. The proposed Center for Lightning Protection at ACCIMT is aimed to fill that void, also focusing on the research and development in the field of lightning and surge protection in Sri Lanka.
Types of damages:-
- Injury of living beings
- Physical damage(due to fire, explosion, mechanical destruction, chemical release)
- Failure of electrical and electronic systems
Types of losses:-
- Loss of human life (and animal life)
- Loss of essential services (electricity, water, telecommunication etc.)
- Economic loss (structures, equipment etc.)
Sri Lanka being a tropical country situated near the equator experiences a high level of lightning activity compared to many other countries. Due to the geographical location, different regions of Sri Lanka are exposed to different levels of lightning activity over the year. By referring Figure 2, it can be seen that Sabaragamuwa, North-Western provinces and densely populated Western province fall into the region of high lightning risk.
Figure 2: Isokeraunic(lightning activity level) map of Sri Lanka
Statistics reveal that there are on average 40 deaths and hundreds of cases of injuries and damage to equipment and infrastructure resulted from lightning directly or indirectly annually in Sri Lanka. In most the occasions the damage could have been reduced if the victims were to follow safety precautions which include correct use of lightning protection equipment.
