I believe that it's called a Jacob's Ladder.  It's interesting to note that
in any of the Star Trek episodes where Spock had to improvise equipment
from archaic (i.e. 20th century) technology, one of those was always
included in the rig.  As far as I know, they do not perform any electonic
function, but are rather a science-museum type demonstration piece, so
I have no idea what function they were supposed to perform for the 
time-travelling Star Trek crew.

I hope this helps
