SF6 End-of-life Distributor for Very High Voltages

A VI will not fail AC Hipot until it is very, very close to end of life. If you look at Pachens curve for dry air you will see the dielectric strength (kv/cm) is very high (About 400kV/cm) from the day it is made (1.E-05 Pa) all the way to 1.E-01 where the dielectric strength rapidly decreases, an AC Hipot cannot tell you if you where you are ...
