Hmm...?
A friend owns a 10uF/5KVW oil filled capacitor, and it is roughly the same size/volume/weight as your cap, or even slightly larger IIRC. For that reason I wonder whether that is really a 190uF/2.8KVW (or higher) capacitor. Of course the thing could contain a string of series connected electrolytic caps, complete with voltage equalization resistors, but I've never come across such a contraption in a sealed case.
If that is a 190uF cap and it really is charged to 2.8KV during normal operation, then the energy contained within would be around 750 Joules.
For comparison of energy contained: Said friend once charged his 10uF oil cap to about 2.5KV, 31 Joules, and deliberately(!) shorted it out with one of those small jewellers screwdrivers. The part of the screwdriver between the capacitor connections instantly turned to fine metal schrapnel, accompagnied by a loud announcement that the screwdriver had handed in its resignation with immediate effect.
Thankfully he was wearing glasses, yet removing the metal splinters from the skin of his face and hands was apparently not too much fun...
He never repeated the experiment.
