The First Woman In 200 Years To Develop A New Lightning Prediction Method Is Malaysian
HAS anyone ever imagined that a Malaysian can be in the same class as historically famous scientists such as Gay Lussac and James Clerk Maxwell?
And, that Malaysian can also be a woman?
For those who do not recall the two famous scientists mentioned above from their secondary school Physics class, Lussac was the French scientist who is known for his law on gas and temperature, while Maxwell is the Scottish scientist known for his laws on electricity and magnetism that all aspiring electrical engineers have to learn. However, the two of them have something in common when it comes to lightning protection, a scientific field developed by Benjamin Franklin a century before them.
Lussac developed what is known as the Protection Angle Method (PAM) in 1823, while Maxwell developed the Mesh Method (MM) in 1876. These methods refer to the techniques of placing lightning rods and conductors on or beside a building to protect it from direct lightning strikes.
When the Western world began developing national lightning protection standards at the end of the 19th century, PAM and MM were included in most of them.
However, as buildings grew taller and bigger in the 20th century, PAM and MM were found to be deficient in protecting these buildings from direct lightning strikes.
The problem was partially solved when a professor from Hungary, Tibor Horvath, developed a new lightning rod placement technique called the Rolling Sphere Method (RSM).
This method was based on his study of lightning strikes on high-voltage electric power lines in the 1950s and it entered most national lightning protection standards in the 1970s.
However, RSM was not able to prevent lightning from striking modern, complex-shaped buildings although lightning rods had been installed as per the method.
Fortunately, a solution has been found in Malaysia by Robiah Ibrahim, a Johor-born maverick woman engineer who lives in Kuala Lumpur, one of the most lightning-prone cities in the world. She burst onto the lightning research scene in 1995 when she co-authored her inaugural paper, “A method of identifying the lightning strike location on a structure”, which was presented at an international technical conference held in the city.
Robiah’s method, later known as the Collection Surface Method (CSM), is based on the observed lightning damage to buildings instead of power lines. CSM made it possible to predict the lightning strike location so that a lightning rod can be precisely placed, a technique that has not been developed by scientists before.
While local academics in lightning protection rejected her findings since she had neither postgraduate qualification nor laboratory experience, an Australian academic and lightning expert who attended the conference recognised her work as a major scientific breakthrough.
University of Queensland’s Professor Mat Darveniza even suggested that CSM formed the basis of a new lightning rod placement method for modern complex shaped high-rise buildings.
In 2003, Darveniza’s suggestion became a reality when the principles of CSM were included in the Australian lightning protection standard, AS1768. This made Robiah the first woman in the world to have developed a new lightning rod placement method in the last 200 years.
It placed her in the same class as Lussac and Maxwell, whose methods are in the standards and applicable today for low- and simple-shaped buildings.
In 2006, the principles of CSM were included in the new international lightning protection standard, IEC62305, thus making Robiah’s method applicable on a worldwide basis. The following year, CSM returned to its country of origin when the Science, Technology and Innovation Ministry approved the international standard as the new Malaysian lightning protection standard, MS-IEC62305.
European experts claimed that CSM could provide up to 98 per cent protection against direct lightning strikes if applied correctly.
However, thousands of Enhanced or Early Streamer Lightning Protection rods are found all over the country, endangering people whenever thunderstorms occur. |

Almost perfect tuuuu 98% protection.....congrats.

Blockbuster dunia science ni,berjuta bangunan tinggi kat dunia ni bakal guna lightning protection dia ni,harap2 dia hire consultant untuk jaga intellectual property tech ni....

So kalau takde phd tak boleh buat keluarkan paper ke journal kah konsepnya? |

sama jugak mcm yg pernah berlaku dulu
masa rakyat bagi cadangan nak turunkan tarif air kat selangor dulu, pemimpin korup kata perkara tu MUSTAHIL.
bila rakyat diberi peluang buktikan cadangan tu bukan setakat turunkan tarif malah jd air selangor jd percuma.
moral of the story
jgn bongkak tapi bg peluang.
jgn sesekali berlagak sombong dan menzalimi.

kalau kiterrr google "lightning protection standard, IEC62305", yg berdasarkan hasil kerja cik Robiah Ibrahim, mendunia gila standard....
bangunan2 sensitif tempat2 pelancar missile US pun guna dahhh lightning protection standard ni, US Airforce pun guna untuk misi2 all weather dia....

New International Standard for Lightning Protection,
IEC 62305
By Richard Kithil, President & CEO, NLSI
1. Present-Day Situation
More than 100 published lightning protection (LP) codes and standards are in use by various countries and by agencies within countries. The USA NFPA-780-2008 has undergone significant upgrading with new information about surge protection. The US Department of Energy recently released M440.1-1, Electrical Storms and Lightning Protection for application to explosives facilities. The US Air Force modified AFI 32-1065 to provide better guidance for critical operations. Yet many US codes and standards represent only minimum levels of safety application: NFPA-780 and UL 96a, by example, have no force of law behind them. At the other extreme, some US documents provide exacting information for specific problems confronting the LP engineer: IEEE 1100, IEEE 142 and FAA STD 019d/e are examples.
Looking outside of the USA’s often-isolated sources of information, a review of other nations’ LP documents is educational and interesting. There is considerable helpful guidance in, for example, Singapore’s CP 33, Australia/New Zealand’s AS/ANZ-1786 (2003), South Africa’s SABS-03, the German VDE 0185, and the British BS-6651. There is agreement and harmony among most national codes as the readers of the Chinese GB 50057, the Russian RD 34.21.122-87 , the Indian IS 2309, and the Polish PN-86/E-05003/01 will discover. Only with “renegade” ESE standards promoted by powerful commercial lobbying groups, such as the French NF C 17-102 and the Spanish UNE-21186, are government endorsements extant for unapproved, non-scientific LP systems.

The Star ada keluar citerrr wanita hebat ni tahun 2014, tahun 1995 lagi kerja dia ni, tapi tak derrrr yg berminat dengan penemuan dia ni, Prof2 yg faham potensi kajian dia ni dari Australia & Singapore, advanced sangat kot masa tu sampai local2 nyerrr researcher tak minat, atau mungkin madey tak nak bagi peruntukan ke apa, zaman nak dekat2 era ekonomi krisis 1998 ni.....
Budak Girl School Tunku Kurshiah kat Seremban ni,kira sekolah high performance gak ni, dia ni electrical engineer, sebab kenapa researcher2 luar tak iktiraf kerja dia masa tu mungkin sebab dia tak derrr PHD dalam kajian lightning kot, tapi basic electrical biasa tu dia ada....

Robiah Ibrahim (aka. Ruby) was born and raised in the southern state of Johor. Nicknamed the “Lightning Lady” by her ex-schoolmates from Tunku Kurshiah College, she studied electrical engineering in a local university when the highly demanding course was still a male-dominated one more than three decades ago.
She became prominent in the scientific world when her inaugural paper on lightning damage to buildings caught the attention of professors from Australia and Singapore back in 1995.
With their support, her work was highlighted to lightning experts in CIGRE, the international technical organisation that studies lightning and high voltage phenomena.
