"HDE" lightning rod in the traditional lightning rod based on the addition of an active trigger system, this trigger system can establish a repetitive high-voltage pulse signal, in the discharge process in due time to produce a continuous discharge path and thundercloud downstream pilot rendezvous, the lightning current into the earth.

"HDE" through a combination of pulse transformer and oscillator to achieve a strictly controlled frequency and amplitude of high-voltage signal emission technology; its energy from the electrostatic field and electromagnetic field and transformed into a high-voltage signal to the tip of the needle, generating a large number of ions, this function so that "HDE" issued by the upstream pilot to advance away from the lightning rod tens of meters or even hundreds of meters and the downstream pilot from the thundercloud to meet the flash, thus expanding the protection range of the lightning rod.

1．2 “HDE” The workflow of lightning rod

Thundercloud formation when the thundercloud prompted the formation of electromagnetic fields between the ground and the clouds, the magnetic field strength at ground level can exceed 14KV/M.

a) At this time, the lightning detector in advance of the discharge lightning rod will detect a certain electromagnetic signal

b) then the detected lightning signal by the sensor will signal transmission to the trigger device

c) trigger device will signal amplification to prompt the next level of high-voltage generator action

d) high voltage generator will generate high voltage to the high voltage pulse generator

e) High-voltage pulse generator will be high voltage oscillation after the generation of electric ions directly to the stainless steel electrode

f) stainless steel electrode tip of the electric ion through the venturi effectively to the tip of the lightning rod.
