Testing an African lightning surge arrestor

An unusual item sent by Frankhe for our entertainment.

In this video I do high voltage tests on the device and then open it to see what's inside.

I did test the little gas discharge tube to see if the electrodes were radioactive, but they weren't.

Maybe use your thermal camera to watch the temp rise. Some of the spark gap arresters used to have some radioactive material to lower the voltage rating.

Parts of Africa have 200 lightning-days a year. Tough work for surge arrestors.
