The thing is called a "jesus stick", though it mostly gets that name 
when used on even larger systems.
It's simply a device to slip in under the anode cap, and connect that 
point to ground, accompanied by a nice "pow".
It needs to be very well insulated, of course.
In large systems, the discharge is accompanied by some vaporized 
metal, and the operator's enthusiastic invocation of the local deity.

There are supposed to be safety resistors to bleed these charges off 
over a period of a few minutes, but they almost always fail due to 
the heat that they dissipate. So, you can't ever count on them, which 
makes their existence in the first place, somewhat pointless.
