Creating an Electrical Wire Corona: Voltage, Amps & Cameras

[jef9911]

Does anyone know what current voltage, amps would be required
to produce a corona around an electrical wire? I gather that this
would also be dependent upon the wire material and size. I have
seen photos of this and would like to do reproduce the process.
What type of camera may these have be filmed with??
