You're wrong, it's right. 8)>>

Where on the secondary was it?
It may be too late to ask: was there previous
damage to the insulation?
(insulation may not be able to 'stop' corona,
it can influence onset.)

The classroom? A Trailer?

Would it be practical to unplug it and put it elsewhere?
Also, how big is this coil, that affects the precautions.
I'd run a dedicated power cord, with shortest possible
dedicated ground for RF portion of coil.
(I'm guessing grounding of the electric supply is a bit
indirect, for the trailer.)

(I get in trouble here with my views on that.... 8)>>:
I don't think its much good for anything but light
shows. Others likely think differently. (that's my view,
debating it is likely OT.))

There are many sites, not sure I'd want to pass judgement
on which are 'good'.
Should 'we' have a condensed list of demos:
Same with antennas
Lighting rod (?)
remote power (diode small motor)
Has been used for vacuum system leak checks.
Has been used for HV source for atom smashing.
I'd spend some time on Tesla The Man...
