HV Lab

The Lightning Innovation and Research Institute LiRi operates a unique equipment: the 1.6 million volts High Voltage Laboratory generates giant electrical arcing of several metres in a highly-secured environment. The lightning conductors triggering times in micro-seconds are recorded and compared to a reference single rod air terminal. The gain measured qualifies the air terminal performance and its compliance to the French and international standards.

The liri lab

The Lightning Innovation and Research Institute is an integrated department of INDELEC, 100% dedicated to innovation. This forward-looking research team of highly skilled engineers provides INDELEC with undisputed R&D abilities and both internal and external training capabilities on lightning protection management and safety equipment installation.
