Detailed Product Description: | A. Ahead of the PULSAR lightning discharge: After years of testing and development, such a lightning rod recognized by the French government, especially promulgated in July 1995 the French lightning protection standards NF C 17-102 specification as part of its application. 1.HELITA (ESE) lightning rod parameters: Characterization of lightning discharge in advance the effectiveness of the main parameters of early discharge time DT, the parameters must be measured in accordance with standard test procedures provided in the French standard, recognized by France LCIE institutions DT is defined as: early discharge lightning rod of the same geometry and Franklin needle under pressure against the discharge time under the same conditions, the discharge time of the lightning rod of HELITA than Franklin needle discharge time of an early 45-155ms. Due to the presence of DT, this power supply, non-radioactive, energy self-sufficiency initiative triggering device, in the Thundercloud comes ahead of launch 15KV high-voltage pulse, and engaged in away from the building at an altitude of thunder and lightning. The one hand, like a lightning rod to extend a few tens of meters, which increases the scope of protection, which is seven times that of ordinary needle, so the application of this needle and needle can be achieved to reduce the count, lower the height of the effect; another , due to lightning at an altitude of ground electric field strength will be reduced by 1/3, or even half, the main thing is, the lightning rod HELITA with active new generation of lightning rod to start the first time, the lightning strike point fell to the buildings may more reduce the lightning also have a good inhibitory effect, especially for a very important building and equipment protection. Two the French HELITA lightning protection radius is calculated as follows: PULSAR lightning discharge in advance the protection of radius Rp = h (2D-h) + DL (2D + DL) is Rp: the protection of the radius h: the protection of the plane to the tip of the vertical distance D: radius of the ball. First, two, three types of buildings were taken 20 m, 45 m, 60 m Early discharge time DL = 106 * DT, DT For the Pulsar 18/25/40/60, DT were taken 18μs, 25μs, 40μs and 60μs.
