1.  Are yout still designing the Lighitng Protection System based on the BS 6651:1999 British Standard?

Did you know that Malaysia has adopted the MS IEC 62305 Part 1 to 4 Protection Against Lightning since 2006 Britain replaced BS6651 with BS EN 62035 from 1st September 2008 What are the main differences between BS6651 and MS IEC 62305?


2.  Should a Risk Analalysis be done for every project?

Yes!!
Explanation of Risk Analysis based on MS IEC 62305 Part 2 Simplify risk  analysis with Dehn risk analysis software demonstration Level of external lighting protection based on risk analysis LPS I, II, III or IV


3.  External Lighting Protection MS IEC 62305 part 3

Three components of External Lightning Protection: Air Termination, Down Conductors and Earthing Rolling Spehere Protection angle and mesh size according to LPS I, II, III or IV Placement of Air Termination Rod based on Rolling Sphere Definition and use of Seperation Distance 'S' Spacing between down conductors according to LPS I, II, III or IV Use of reinforcement bars as down conductors Welded Joints v/s clamped Joints v/s Bound joints v/s latched joints Types of Earthing; Type A or Type B Equipotential Earthing


4.  Save up to 33% costs of material and labour by knowing the materials and installation methods while still complying to MS IEC 62035 standard.
LPS Materials and conditions of use. Table 5 MS IEC 62305 Part 3 Material, configuration and minimum cross-sectional area of air-termination conductors, air-termination rods, earth lead-in rods and down- Conductors. Table 7 MS IEC 62305 Part 3 Material, configuration and minimum dimensions of earth electrodes. Table 7 MS IEC 62305 Part 3


5.  Internal Lighting Protection MS IEC 62305 Part 4
Should SPD (kA) discharge capability specification be 160 / 200kA - with "super low" let through voltage ?? Does a SPD rated 200kA able to withstand a 200kA surge - 10/350us or 8/20us??? What International Standard is applied - IEEE (UL Std), BS Std, AS Std or the IEC Std? What is the differences? Malaysia had adopted the IEC STD for Risk Analysis and SPD application correct application for Lightning Current Protection (10/350us) and Surge (Transient) Current (8/20us). Differences in energy level For 10/350us or 8/20us?- video show Terminology :- per mode, per phase, per conductor, total surge, Imax, I imp, In etc…Do IEC Std recognize such phases? Differences and Comparision in Class I (Type1), Class II (Type2) and Class III (Type3) for ALL types of SPD - Spark gap technology vs MOVs and Coordination - Video show "SHORT CIRCUIT CURRENT RATING" or Short-circuit withstand - Isccr of SPD IEC Std Testing required SPD to withstand the Prospective Short Circuit Current at point of installation - the "short-circuit withstand" of SPD must be rated eg: 50kA rms or 25kA rms with the coordinated fuses Is the Fuses / MCCB recommended by supplier correct??  To ensure correct Fuses / MCCB rating, IEC STD have recommended calculation and value against I crest (kA) for 10/350us and 8/20us
