What is the Australian standard for lightning protection?
AS/NZS 1768:2007
The AS/NZS 1768:2007 Lightning Protection Standards Australia provides guidelines for the protection of persons and property from the hazards of lightning.

Is lightning protection a legal requirement?
Do I need lightning protection? It is not a legal requirement for all buildings and structures to have lightning protection, according to the risk control publication RC35 ‘Protection of buildings against lightning strikes’.
How do surge protector devices work?
When a transient voltage occurs on the circuit, the SPD moves into a state of conduction (or low impedance) and diverts the surge current back to its source or ground. This limits or clamps the voltage to a safer level. After the transient is diverted, the SPD automatically resets back to its high-impedance state.
How does a lightning protection system work?
A lightning protection system includes a network of air terminals, bonding conductors, and ground electrodes designed to provide a low impedance path to ground for potential strikes. Lightning protection systems mitigate the fire hazard which lightning strikes pose to structures.
How do you calculate lightning protection?
Length of Building (L) = 60 Meter. Width of Building ( W ) = 28 Meter. Height of Building (H) = 23 Meter….Calculate Lightning Protection for Building / Structure.

How often should lightning protection be tested?
12 months
Whilst BS 6651 recommended that lightning protection systems should be inspected and tested at fixed intervals, preferably not exceeding 12 months, the maximum interval under the new standard is four years; it may be convenient to reduce this to two and a half years to fit the quinqennial inspection cycle, with an …
What is level 4 lightning protection?
Part 4: Electrical and electronic systems within structures. BS EN/IEC 62305-4 (part 4) covers the protection of electrical and electronic systems housed within structures. It embodies what Annex C in BS 6651 conveyed, but with a new zonal approach referred to as Lightning Protection Zones (LPZs).
How much does it cost to install lightning protection?
Installing lightning protection systems in the home costs between $434 and $2,533, averaging most homeowners $1,482. The cost ranges from $100 for just a surge protector to over $3,000 for rods and grounding system.
