Just looking at my Megger reg trade mark, made by Evershed & Vignoles, Acton
lane works, Chiswick, London W4. This one must 50 years old (brown
bakerlite). It has a hand driven generator to generate the high voltage.
Wow.... what does a 300KV voltage tester look like...how does it generate
that high of a voltage?
