Bertan/Spellman 225 20kV HV Power Supply Teardown and Experiments

In this video, I did a teardown of a Bertan 225-20R 20kV high voltage power supply and conducted some interesting experiments. Teardown details and pictures can be found on my website: http://www.kerrywong.com/2016/11/19/b... I did a teardown of another Bertan HV power supply a while ago (205A-05R): http://www.kerrywong.com/2016/11/13/b... And for more information on the static field meter I used in the video, you can take a look at my post here: http://www.kerrywong.com/2016/09/06/t...
