预放电时间和保护半径 (Rp)
The Pioneer LY-ESE 3.0 early streamer emission lightning rod has passed all standard tests.该产品的预放电时间为:
△T=60μs
根据法国标准NFC17-102:2011,
当h≥5m时:
Rp(h) =√2rh - h² △(2r △)
当2≤h≤5m时:
Rp = h*Rp(5) /5
Rp: Protection radius on the horizontal plane under consideration,
h(m):先锋LY-ESE 3.0避雷针尖端与被保护物体顶部的高度差,即有效安装高度。
r(m): 20m, 30m, 45m, 60m, calculated based on the risk analysis (NFC17-102:
2011 Appendix A) to assess the protection level I, II, III, or IV at the site.
△ is the upward leader distance: △L = V (meters/microsecond) * △T (microseconds), experimental data
show that this is equivalent to the efficiency obtained during the ESEAT evaluation test.
