Active early discharge lightning rodWorking principle of PDC series：

The PDC series lightning rod mainly absorbs and stores energy from the natural electric field through the exciter EXCITERS. The reflector Reflector and lightning rod tip have good electrical connection with the ground and are in an equipotential state. So usually, there is an electric field strength between the exciter and the emitter. Before a lightning flash occurs, the electric field strength increases rapidly, and the potential difference between the exciter and the reactor is roughly equivalent to the potential between the thunderstorm and the ground. The rapid increase in voltage drop between them will cause ignition at the tip and ionize the air around the tip, forming a tip discharge phenomenon.

Central collection rod and exciter of lightning rodThe rapid increase in electric field between ExcitERS causes ionization of the air at the tip, which can be discharged in a very short and accurate time. Due to the presence of a large number of electric ions, the natural Corona effect is reduced, creating an expected upward discharge channel that can quickly/safely intercept lightning and safely release it to the ground.
Calculation formula for the protection radius of PDC active early discharge lightning rod

set upIf the start preemptive time of IPDC is Δ T, then the preemptive distance of the upstream leader Δ L=V * Δ T
according toThe calculation method provided by NFC-17-102 standard calculates the protection radius Rp according to the following formula:

The distance of D electric shock depends on the level of the protected building. For Class I, II, and III protected objects, the D values are 20m, 45m, and 60m, respectively.

H is the height from the top of the lightning rod to the protected plane.

Δ T is calculated and evaluated through testing, as shown in the table above

V=106m/s

ΔL=V*ΔT
Note: Currently, there are no testing and acceptance standards for early discharge lightning rods in China. Please follow the height radius of the lightning rod（Calculation of relevant standards in GB50057 "Code for Design of Lightning Protection of Buildings".
