Congratulations on the genset. Is it 30hp? On 6/1/2014 9:07 PM, Jim Mora wrote:
Hello Tesla Friends, I have been away for a few years on other quests but still have all my Tesla Coil stuff. Recently, I finally got my 3P 208v wye 15KW <cont> Diesel genset running. I have a Cold War era Raytheon 3P DC charger that uses (6) 8020 Tube rectifiers - very Frankenstein -ish! The output is through a very large Inductor (Says 150 Henries) and is 24KV(-) the (+) side comes from the filaments, the minus is on a 12" standoff insulator! Anyway, I plan to wind a 12" form (thin wall PVC) to a 5:1 ratio. I have (2) unused .1uf General Atomics large pulse duty Caps @ 50KV. I realize the out power will be a linear rise as BPS goes up. I haven't tried to predict resonate charging nor want it per say, a visit to Richie Burnett's site is needed. * I do "not" have a suitable Spark Gap and will either build one or buy one. I have an ample supply of G10 that is suitable but lack machining tools. I also have (8) .5" x 2.25" pure tungsten slugs (intended) and numerous .25" which probably wouldn't stand up for the rotor. There is no rating of current I/0 on the transformer / supply tank. The internal transformer is a 208 wye in ?HV delta out, there is also a assumed isolated internal filament transformer with 1 P 120v input I see that (1) 8020 can run at 100 - 750 ma 2A peak. Anyone want to do an educated guess on the output of the supply limits? BTW the + terminal is on a close to case standoff so it is meant to be -24KVDC above ground out. I have the schematic with no ratings stenciled on the tank. It is oil filled. Thanks Much, Jim Mora You can contact me off list if you like: wavetuner@xxxxxxxxx I also have a 14,400 5VKVA Pig as well as a large GE potential transformer of the same rating. So if the DC charging fails, its back to classic design. _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
