Lightning Protection Calculation Repack

For an isolated rectangular structure: $$A_d = L \times W + 2 \times H \times (L + W) + \pi \times H^2$$

The most robust and universally accepted method involves "rolling" an imaginary sphere over a building model. Any point the sphere touches is a potential strike point that requires protection. IEC 62305 Lightning Protection Overview | PDF - Scribd lightning protection calculation

For a standard LPS, the recommended earth resistance is typically . For sensitive equipment or high-risk facilities, this is often lowered to < 5 Ohms. For an isolated rectangular structure: $$A_d = L

Before designing a protection system, you must determine if protection is needed. This is done using a comparing components like: this is often lowered to &lt
