I'm still trying to pluck up the courage to get the 1kV supply working, without a schematic.
I've got an UltraVolt 0-1kV adjustable DC to DC convertor I picked up for a song a while back. The plan is to, when I get around to it, stick it in a safe case with a pot on the front to provide an HV source for things like high resistance measurements and other general TEA purposes. When I got it I obviously needed to test that it was OK and worked properly and I don't mind telling you that I was a bit trepidatious about having a live, uncased, 1 kV source out on the bench.
I once was tasked with "There is no power in the food court on the festival camping, please investigate". Well, I jumped on the ATV, a colleague jumped on behind me, and we went, with multimeter and torch in hand to investigate. (it was so late in the evening that even in summer Sweden, it's dark outside)
The problem was traced to phase L1 being out (it's always L1. Why? Well,
every idiot who builds a kebab stand on wheels puts the deep fryer AND the fridges/freezers on Phase 1, the kebab rack on Phase 2, and the LED festoon lights and a phone charger on Phase 3. Put four of those in the same food court / fast food area, give them a 16A 3-phase outlet each and watch the fuse for L1 pop.) L1 was out even on the part of the temporary construction site distribution cabinet that requires IEC 61010-1 Class IV meters. Upstream we went, and traced the AKKJ 3x90+90 (90mm
2 PVC insulated, PVC sheated three phases plus PEN braid aluminium cable, direct burial class) cable through the more or less sanitary conditions it had been laid, to the permanent distribution cabinet in a small forest near by. Here, it was pitch black. My helper held the Maglite, and I opened the cabinet. Inside, there are naked bus bars. And probably some 630A upstream fuses. I measured across the bars, all phases OK, found the fuse link that was blown, and pulled it. The puller tool is a sort of crossover between a set of forceps and a speculum, with a shield midway, and made of glass-reinforced plastic.
As I was somewhat focused on this, a festival visitor came up to the fence that held campers inside the festival (we were on the outside) and since he was obviously bent on relieving himself, we discouraged this, being in the danger zone of said activity. He complied (slowly, because he was properly drunk) and asked what we might be doing.
I simply answered "I'm staring at DEATH", fitted a new fuse on the puller, plugged it without too much arcing, closed the cabinet, and went to blackmail the food court operators for coffee.
