Protection Radius Calculation

According to the French NFC 17-120 standard, the lightning rod tip should be at least 2 meters above the horizontal plane of the protected object.

When h < 5m, the protection zone of the lightning rod must be obtained by depicting an electromagnetic model, as shown in the protection radius table;

When h ≥ 5m, the protection radius can be calculated using the following formula:

Rp =  h ( 2 D –  h ) + ΔL ( 2 D + ΔL )  

Rp — Protection radius (m);

h  — Distance between the lightning rod tip and the highest point of the protected object (m);

D  — Rolling sphere radius (m); According to the French NFC17-102 standard: Class I buildings D=20m

(GB50057-94 specifies D=30m), Class II buildings D=45m, Class III buildings D=60m;

ΔL— Upward interception distance of the lightning rod (m), ΔL=V (m/μs) × ΔT(μs), where V

is the average leader propagation speed, approximately 1 meter per microsecond, and ΔT is the early streamer emission time of the lightning rod.
