II. Lightning protection for high-rise buildings:
Through field surveys and works not included in the lightning protection of other works should calculate lightning protection systems for buildings. The high-rise buildings are now commonly used lightning arresters first ray religion. In this work we use the first lightning-ray its direct HELITA- France.
1. Earlier emission lightning bolt leader gets PULSAR18 early (the early streamer lightning EMISION (ESE)):
Is the PULSAR is designed and manufactured by the French firm HELITA-. This is a direct lightning protection system the most advanced in the world today with the certification of invention patent in 1985. 2003 emission technology development soon generation IV. Solution design and engineering firm was HELITA standards committee of the French National Safety accept a common national standard NFC 17- 102/1995 and this product has been certified the quality of the French LCIE valid worldwide, BSI British, Korean and MINT KERI of Malaysia together with the certification test at the factory, at the Central Laboratory Electrical Industry Country France (LCIE), at room Electricite De France experiment "Les Renardieres - EDF", and in the laboratory "DES DE DECHARGES physique". PULSAR lightning protection system consists of three main parts:
- Top PULSAR18 lightning
- lightning conducting copper.
- Lightning grounding system and ground safely.
1.1 Top of lightning PULSAR18:
a. Operating principle:
First lightning PULSAR receive the necessary energy in the atmosphere for storing electrical charge in the cylinder elected. PULSAR will collect energy from the electric field surrounding areas during storms range from 10 to 20,000 V / m. Path initiative started as soon as the electric field around exceed the maximum value to ensure lightning risk is minimal.
It emits a voltage signal with a high amplitude, frequency creates certain road Lightning initiative led upward while at the same time reduce the capacity of lightning around the receiver ie for reducing the time required emits lightning proactive path toward continuous on.
Controlling the release of ions right time: Ionisation equipment allows ions generated in a very short time period and at the appropriate time special, just fractions of seconds before the lightning discharge, thus ensuring timely conduct lightning, precision and safety.
PULSAR is active devices do not use electricity, do not cause any noise, just within few Qsd impact before the lightning actually hit down and be effective in the long term .
