SYNOPSIS



Design of Lightning Protection System based on the MS IEC 62305 standard.

Malaysia has adopted the MS IEC 62305 Part 1 to 4 Protection Against Lightning since 2006 replacing the previous BS 6651 which was withdrawn on the 31st Aug 2008

Should a Risk Analysis 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

External Lighting Protection MS IEC 62305 Part 3
Three components of External Lightning Protection: Air Termination, Down Conductors and Earthing
Rolling Sphere 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 Separation 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

Save on costs of material and labour by knowing the materials and installation methods while still complying with MS IEC 62305 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, airtermination 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 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) waveform and Surge (Transient) Current (8/20us) waveforms

Differences in energy level for 10/350us or 8/20us?

Terminology: per mode, per phase, per conductor, total surge, Imax, Iimp, In etc… Does the IEC Std recognize these terminologies?

Differences and Comparison 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 e.g. 50kA rms or 25kA rms with the coordinated fuses

Is the Fuses/MCCB recommended by supplier correct?? Refer to MS IEC 61643-12 Annex P Informative guideline for the calculation and selection of backup fuses for different types of spd
