Cesivid [716 286 7610] makes special high pulse energy absorbing
resistors. They are not inexpensive.

Not a fuse. Only a fault current limiter. If the glitch resistor breaks
down during the glitch, it does not limit current, so it should be
replaced by a resistor that is more capable.

A Clarostat 10w 10 ohm glass coated wirewound resistor will discharge
2800v and 25uF without harm. Above that potential, I would use two of
them in series to reduce the voltage gradient. With glitch resistors,
mo' longer is mo' betta.
