Showering Arc Noise Generator

[Ccorson]

I have this and no use for it and what was it for

A conversation starter?

 

[Ccorson]

Just curious what it’s for and if I have any use for it

The expression "showering arc noise generator" does not make any sense.

Where did you find this thing?
Can you post a picture of it?

Curiosity got me. Post #9 might give a better idea here:

Instrument to inject noise on mains

Hi, Does anyone know of some test equipment that I can inject noise (ideally configurable) onto the mains with? Thanks Steve

It was homemade by a company that manufactures rail road track maintenance equipment, at the time they used quite a few circuit boards and other rather obscure electronic do dads and gizmos

Well, I think that I have learned something today.

Look here:

EMC Testing Part 3 – Fast Transient Burst, Surge, Electrostatic Discharge

and have a read about EMC Fast Transient Burst testing.

In the dim and distant past, when I had to do some EMC testing as part of my day job, Fast Transients was a test which caused quite a few problems for some of out older equipment.

I had not seen the expression "showering arc" before today but it seems to be used to describe the arc which is produced when switch contacts are made/broken.

So, now you have some idea what it is used for, but what you can do with it? Who knows?
Rip out the insides and build something useful into the case maybe?

Might be Ok for testing Afdd's.
Arc flash detection devices, which are being made mandatory for certain electrical installations here in the Uk.
Does it have any interesting gizmo's inside.
