[Test-Equipment] Another boat anchor - Del Electric High voltage supply?

[Sheldon Daitch]

I just looked at the lead for the Hipotronics HD100 unit we use for our
tube and capacitor testing and it uses a section of Saxon M17/163-00001
coaxial cable, essentially unswept RG-213 per the Allied listing.

Rated RMS voltage is 5 kV, but since the hipot tester will go upwards to
40 kV, the insulation is quite capable.  The real trick with the cable is
to have a long section of the insulation not shielded, to reduce the 
leakage
path from the center conductor to the shield.  The Hipotronics cable has
about 5-6 inches or so of unshielded cable in the connector going into the
test set and the same at the clamp end of the cable.
