HV - Screens

Click on the photos for bigger picture. 
Screens of insulating material between the terminals of your coil and the walls can dramatically
reduce arcovers to the wall. They represent an easy solution to making bigger sparks inhouse.
The method is quite old. I found it in the book "Elektrische Hoechstspannungen", of
Dr.A.Bouwers, Springer Verlag, Berlin 1939.
