New Lightning Protection and High Current Products

While NexTek takes pride in having industry leading coaxial lightning protectors and expertise, it's always interesting to see how much ingenious engineering went into preventing lightning damage in the early days of coax cabling... Despite primitive and error prone concepts.

The protector illustrated worked by providing an arc path from both the input and output cable to the grounded sphere in the center. The input and output coaxial center conductors are through connected with an inductor to reduce the let-through energy. This entire device is housed in a steel box.

What would the performance be for this "cable hut"?
      RF performance: Usable performance probably to 1 MHz
     
Lighting Protection: Very high transient ampacity of over 50 kA, however, let-through likely a very high 15kV / 1J
     
From such humble beginnings, we bring forth protectors that would make Dr. Lodge proud!
       
     
The Engineer's Guide to Lightning Protection
     

THE SHINING. An extraordinarily large—about 100 meters in diameter—object presumed to be ball lightning was caught on film by a park ranger in Australia. It lasted surprisingly long, about 5 minutes.

 

Written by Dr. Oliver Lodge, a Professor of Physics at University College in Liverpool, this book still provides fascinating insights in LP technology. Some of the methods described are still in use today!
