EDM noise

[ErnieD]

Hi,

Can anyone tell me if an Sinker EDM machine used in a home shop on a 120 VAC line will create any sort of interference on the line. I would not want to mess up anybody's TV or radio programs.

If there is an interference problem, what can be done to remedy it?

Thanks,

Ernie

It shouldn't really effect the line, but to be on the safe side use a line conditioner (salvage one from a old computer supply). The thing you have to worry about is RF,radio frequency. The spark gap is basically the same thing that the old Marconi/Tesla
short wave transmitters used.

Back in the old days when folks got their TV reception from the air waves you bet there was a lot of interference problems.
I had a guy that had a machine that I could not figure out why it would drop out of cycle after he went home at night.
Found a little hole broken in the window near the machine. Caught the neighbor sticking a rod through the hole and hitting the button.
He was real pissed cause it messed up his TV. But the zonning was right for the business. I think he put lead foil around the sides and top of the machine to block the RF.
I know there are written instructions and drawings of how to contain an EDMs RF waves in a residential area.
