standardspg_img_5NF C 17-102: Protection of Structures and open areas against Lightning using early streamer emission air terminals

When specifying the ABB Hélita pulsar system, it is necessary to mention the product specification, NF C 17-102, as this modifies EN 62305 in several ways concerning the number of down conductors used, Powercom Solutions engineers have over 15 years experience in design, supplying, installation, and testing of the ABB Hélita pulsar in Ireland.

A major cost saving is made on utilisation of the faraday cage installation, down conductors and earth pit locations and major cost savings on the builders works on a existing building.

The Hélita Pulsar system has been approved by Environmental Consultants, Carbon Footprint Ltd. Directors of the Carbon Footprint sit on the BSI Emissions.

Hélita enjoys a worldwide reputation as a foremost specialist in direct lightning protection. Established since 1932, the organisation’s commitment has always been to offer truly effective systems and designs, providing the highest level of safety and effectiveness in lightning protection. Over the years, Hélita has emerged as the world’s leading manufacturer for Early Streamer Emission (E.S.E) lightning conductors.

These state of the art technologies have been designed on the basis of a series of patents registered jointly by Hélita and the French National Research Organisation (CNRS). The collaboration also introduced a method of testing in high voltage laboratory, used as a procedure of evaluation of the Early Streamer Emission air terminals in Appendix C of standard NF C 17-102, to assess the efficiency of an E.S.E.

Apart from its distinguished credentials, Hélita has also proven its commitment to research and development. It continuously sets new benchmarks for the efficiency of lightning conductors with the CNRS and has undergone testing in renowned laboratories internationally and obtained certifications with the relevant authorities as follows:



  • LCIE (Central Laboratory for Electrical Industries), France
  • KERI (Korean Electrotechnology Research Institute), Korea
  • BSI (British Standard Institute), United Kingdom
  • WHVRI (Wuhan High Voltage Research Institute), China
  • CEB (Bazet High Voltage Laboratory), France

The ABB Hélita pulsar range with increased initiation advance performances represents further progress in terms of protection, operating autonomy and ease of maintenance.

These advancements reinforce Hélita’s position as a global leader in direct lightning protection with over 350,000 installations throughout the world.
