Calculate Building Lighting Protection
This excel spreadsheet contains lightning protection calculations for three buildings: 1) A TG building that is 36m x 28m x 23m, with a collection area of 5613.9 sqm and a probable number of yearly lightning strikes of 0.0387. 2) A cooling tower that is 40m x 15m x 12m, with a collection area of 2372.39 sqm and a probable number of yearly lightning strikes of 0.01637. 3) A boiler building that is 33m x 20m x 50m, with a collection area of 13813.98 sqm and a probable number of yearly lightning strikes of 0.09532. For each building, it calculates the https://en.wikipedia.org/wiki/Lighting

FAQs:
How to calculate lightning protection level?
Lightning Arrester Coverage Area Calculation | Axis Electricals
d = 2 * √(2rh – h²)
d is the distance between two air terminals,
r is the rolling sphere radius as per the applied Level,
h is the air termination height over the horizontal plane.
How is lightning protection measured?
The ‘Zone of Protection’ offered by an air termination network is considered to be 45º for heights up to 20m. Above this height, the zone of protection is determined by the ‘Rolling Sphere Method’. This involves rolling an imaginary sphere of 60m radius over a structure.
How do you calculate building lighting load?
How to Calculate Lighting: An Authoritative Guide (2023)
With that in mind, here’s how to calculate lighting load:
Obtain your electrical circuit’s amperage from your circuit box.
Multiple your amperage by your voltage limits.
Once you have your power load, subtract all other loads from that to know how much you’ll be left with for lighting.
