Collection Volume Lightning Protection System (CVM)

• Based on collection volume method, electric field intensification 

• Extension of rolling sphere method, conventional system considering the competing features of building 

• Non-radioactive technology

• No external power required 

• No moving parts 

• Streamers released only when the ambient field can sustain leader initiation and propagation 

• Protection radius based on protection levels from 84% to 99% 

• Dynamic response to the approach of a lightning downleader 

• Design software for adequate placement for terminal for optimal protection 

• Only one down conductor required upto 100 m
