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.
