Using a toroidal transformer as a mod transformer Part II

<< < (10/10)

w4bfs:
you might consider a string of varistors (high tech) across the secondary or a spark gap (low tech) for peak voltage protection

In Electric Radio mag the spark gap spacing (in inches) between 'horns' of the spark gag = (V - 350) x 10 -5  

example: want a spark gap to fire at 2500V so the spacing would = (2500 - 350) x 10-5  = 2150 x 10-5  = .0215 inches

can set using feeler guages

By the way, I got around to dismantling one of the Antek low voltage toroids ... seems like all winding sets are bifilar wound with extra insulation ... makes sense when you consider how the hipot test is specified .... if only 2 layers of Formvar are the insulation between the bifilar twins then the question that gets begged is how do the high voltage windings survive when hooked up as full wave center tap ? (in series)  so I'm still wondering about survivability as a high voltage mod xfmr ...73 ... John
