Deployment of effective device underscored to save equipment from lightning, power surges
Sunday, 8 July 2007
As industries in Bangladesh have become more dependent on increasingly sensitive equipment, they need proper protection from unexpected lightning strikes and dangerous over-voltage surges, experts told a seminar, reports UNB.
They said defence sector industries and business houses in Bangladesh need lightning-protection and grounding solutions as the country remains highly vulnerable to lightning strikes during monsoon and pre-monsoon periods.
A day-long seminar on "Lighting, surge protection and grounding solutions by applying modern concepts, technique and technology" was jointly organised by Techno Source and ERICO Lightning Technologies Pty Ltd, Australia at Spectra Convention Centre in the city Thursday.
Phil Jones, product manager, Surge Protection Division (Asia/Australia), presented various slide-shows, technical examples and proper solution plan, and showed various ERICO protection equipment at the seminar.
With over 60 years of research, testing and product development, ERICO found that no single technology can fully eliminate vulnerability to lightning and surges. The ERICO, therefore, provides a six-point total facility protection plan by integrating several concepts.
The six-point plan includes capturing the lightning strike on air terminals at preferred points, directing the strike to ground via down-conductor safely, dissipating the lightning energy into the ground with minimal rise in ground potential, eliminating ground loops differentials by creating a low-impedance and equi-potential ground system, protecting equipment from surges and transients on incoming power lines to prevent electronics equipment damage.
Some 50 representatives from various government and private organisations took part in the seminar.
The participants included Md Maksudun Nabi, OC of Air Force Communication Unit, Md Towhidul Islam of Air Force C&E Directorate, Md Neamul Hasan, deputy director of the Directorate of Naval Weapon and Electrical Engineering, Naval Headquarters, Abu Zafar Mohammad Salahuddin, Bangladesh Army, Signals Directorate, Shamim Ahmed Mazumder, deputy director (Technical) of Special Security Force, Chief Adviser's Office, Syed Mohteshamul Islam, Manager (Commercial) of NIKO Resources (Bangladesh), Md Manzurul Haque, Chief Engineer, Reactor Operation and Maintenance Unit (ROMU), Atomic Energy Research and Establishment, Shah Hasan Haider, garrison engineer, MES, Air Headquarters, Mustafizur Rahman Khan, superintending engineer, MES, Army Headquarters, ATM Zia Hasn, Station Engineer, Bangladesh Betar, Abu Nasir Md Mynul Hossain, Rokon-Uz-Zaman, Technical Implementation, Grameen Phone, Yehia El Hamalawy, Network Deployment, Banglalink, and Mohammad Mahmudul Haque, DGM, Teletalk.
