I'm getting ready to build my first tesla coil, most likely from a kit. I've done a lot of reading and research, and feel comfortable overall, but there is one thing that I couldn't find much solid info on.
How concerned should I be about any electrical voltage or interference potentially traveling back through my households electrical system and damaging things elsewhere in the house? For example...
1. What would happen if a stray spark happened to strike the main power cord, or the primary coil or something else? A quarter million volt arc, striking or otherwise getting introduced into a 120 line just sounds bad, could this potentially fry things across the house? Are there any simple affordable steps that can be taken to prevent this (if it is indeed a concern)? Perhaps some sort of choke or filter to prevent any voltage/current being back fed?
2. What about RF interference? I've heard that tesla coils can potentially produce RF interference on the household ground line, potentially interfering with other things plugged in. I once saw it advised not to have a computer plugged in while a tesla coil is running due to RF interference. Is this really a concern? Can anyone elaborate a little more about what exactly causes this RF interference. And also, are there any steps that can prevent this?
Just brainstorming, perhaps if I ran the tesla coil off a modified extention cord which had a splice or pigtail coming off its ground cable, going to a completely seperate ground rod I would pound into the ground nearby. That way it would still be connected to the main ground, but there would be a second ground rod as sort of a first line of defense to hopefully catch the vast majority of anything bad, before it even reaches the main ground. Or perhaps a better idea?
I might be over paranoid, I've seen people running tesla coils in their living rooms, around all sorts of electronics, with no major precautions seemingly taken, and no major issues. However I don't want to take chances, I want to gain the skill and knowledge to fully understand this, and make my safety system as bullet proof as possible, so any input would be appreciated.
Thanks.
