Seminar on Lightning and Surge Protection MS IEC 62305

Seminar on Seminar on Lightning and Surge Protection MS IEC 62305

Date: 15th September 2015 ( Tuesday)

Time:   9:00am to 5.00 pm

Venue : IEM Penang Branch Secretariat


Lightning phenomena’s are mega – atmospheric electrical activities which may cause fatal injuries and extensive damages to properties and services. The Malaysian Standard on lightning protection, MSIEC62305, had implemented since 2007, however not much adoption on this standard for current engineering design. This seminar aims to clarify the importance of the air terminal placement and others parts of lightning protection equipments are according to MS-IEC62305 as an effective tool in lightning interception in order to effectively protect structures from being struck and damage by lightning.

In the first year after graduation, he served as Sales Engineer in Tamco Electrical & Electronics Sdn Bhd based at Selangor. The next 10 years, he joined WJ Furse UK – Thomas & Betts/ABB as Business Development Manager and serving in Far East Asia region, specialized in selling/designing in Lightning Protection industry, to support R&D Engineer in product development and also to support customer, consultant, distribution channels in embedded design or engineering calculation. Mr Vincent Loh leave WJ Furse UK and joined Tyco Electronics – TE Connectivity as Country Sales Manager to provide service on medium to high Energy/Voltage cable & accessories. His current portfolio is now in the Asia region serve as Executive Director for ABRE Group of Companies. He has more than 21 years professional experience and practical expertise in industrial product, sales & application for electrical, lightning solution, utility earthing, explosion proof & industrial products. He
also have strong network contacts in Electrical Consultant application segments, Utility and Oil & Gas related field’s application.
With his strong analytical, quantitative, and problem-solving skills, Mr Vincent Loh is good in handling
channel partners, agents & distributors network
