In this video, we’ve explained the science behind the Protective Angle Method for Lightning Protection Design as per IEC 62305. In this video you will understand:
What exactly is the Protective Angle Method?
How does the Protective Angle function?
Which angle should you use for optimal protection?

Let’s Dive deep into the Protective Angle, a mathematical simplification of the renowned Rolling Sphere Method, and understand its significance, especially for simple structures.

The angle depends on the Class of the Lightning Protection System and the height of the air rod. It is determined from Table 2 from IEC 62305 part 3. For simplifying it further, we have shown the table of protective angles for air termination rods that are up to 2m in length.

Please note the Protective Angle and other methods like the Rolling Sphere and Mesh Method should always be executed by competent engineers.
