TDRs pick up sudden impedance changes. I don't think any are made specifically to pick up this situation.

Outlets are cheap. By the time you pull one to check it out, you may as well put a new one in. You can get sparking from plugging something in that's on - that's normal. I've seen outlets that were installed poorly and left loose - wiggle them and you can short and trip a breaker. Or, the receptacle could be worn so it doesn't make good contact with the plug all the time. Even a "small" problem is cause for concern,because insulation can eventually cook or a conductor can oxidize and that makes it something of a time bomb.

I'd just replace the outlets and get after what's happening with the 3 way. Just hope it isn't rodent damage - that can mean a much bigger problem.

Yeah, that one is around $100 more than the one I purchased, and it has exactly the same functions as the Extech analyzer I have. I have used mine extensively to find problems (loose connections, faulty wiring, nail/screws in nm cable, faulty GFCI outlets, etc) and make things much safer for any and all occupants. If more folks had this tool, I honestly believe there would be fewer house fires due to electrical issues.

Re: Checking Wiring Integrity


How about swapping out all your breakers to arc faults? I did that for the whole house, not just bedrooms, and I sleep well at night. They can be had on ebay for about $25 a piece when bought in bulk.

Watch for nuisance tripping if you live near radio transmitters. They may send you a filter if you report this problem.
For troubleshooting, Siemens makes a device to do this.

Re: Checking Wiring Integrity


The only test you can do at this time is an insulation resistance test, which that is accomplished by applying voltage for a certain amount of time to the wire, but a normal volt meter is not a right tool for that. Technically, it is a form of destructive testing. I recommend you to discuss your problem with some Electrician professionals.
