I have been following this and I think I might have something to add.
Are you near a radar dome for an airport or a military base?
The reason I ask is, I used to work for Volvo Corp. help desk after many years as a line tech at a dealer. We got a call from one of our dealers and it got escalated to a local field rep about a vehicle would stop running and would restart right away, the rep. came to find out it was always at the same spot on the road. He did some research and found out the car would stop running right in front of radar dome for air traffic.
he did a little shielding on a component (I can't remember what it was.)

My point is---- could it be another external EMI source?

Maybe not "EMI" (fully), it would be "RFI" (radio frequency interference)

It's just a thought

Here is a funny story. Years ago before my house was rewired if you so much as changed a light bulb or plugged something in it was common to get a bit of a blue flash. If you walked on the roof you would get sparks under your shoes.

When I had the house completely rewired it was found out that the house had no earth to ground what so ever. I always laugh a bit when I look back on that.

I am a welder and machinist. I have had times where I have had tingling sensations in my arms when leaning on a metal welding table. Every issue I have had like that has been due to a grounding fault or a poorly placed earth clamp. There is a whole section on high frequency radio interference in the manual of one of my welders and it all talks about the importance of having everything grounded properly.

Im no electrician but I would definitely be looking at grounding and ruling that out.

 

[Rhyno]

This subject is somewhat up my alley.

Simple question to Rhyno......what is being interfered?

This list is relayed without any importance for complaint position.

a. Data delivery upon partially shielded CAT6 cables.
b. repeated Device failures of internal components of HDMI splitters and other similars with all of them being commonly grounded at devices and supply lines.
c. Memory capture and temporary device malfunction upon wireless AGM sensor with NFC delivery. I have captured data charts of this failure pattern.
d. temporary Smart TV digital airwave malfunction as train or traffic drives past.
e. temporary Smart TV menu and operation malfunction.
f. temporary Computer operation and data saving malfunctions.
g. FM radio signal malfunction on eastern side of home either working or not.....Never a static sound.
h. Sheriff dept voice radio malfunction in same area.
i. Sheriff vehicle bluetooth data relay malfunction in same area from body mic and camera to vehicle.
j. 146 Mhtz area malfunction with a video captured rolling signal.
k. Multiple personal devices' Bluetooth malfunction....with multiple versions of wireless computer mice and other devices.
l. When sitting directly under the grouped in attic electrical lines, Mac Laptop malfunction in operation, file tranfer to USB, and finger slide pointer.
m. Repeated Screen mirror display and connection malfunctions with same manufacturer of both phone and tv.

As I write this and revisit the happenings and locations within the home, I further suspect electrical resonance and the need for added capacitors.

I look forward to your addition.

Thanks for the input and relay.

I agree with everything you have relayed as I have experienced these things, too. As said in the earlier long relay of happenings, I have added ground rods and have cleaned up ground connections in multiple areas.

Cheers!

 

[Rhyno]

I would try to work on one type of interference at a time. Have the interfered with item on and working all the time and monitored. Keep a journal of the type, timing and duration of the interference.

Lots of things can cause interference and lots of things are not required to be free from interference.

Bill

Thanks.

 

[Copymutt]

Sorry to hear about the planet your living on.
Dirty power, isolation transformer fix. Good luck w/ the $ for that. I have done it for discreet circuits. Long shot here, kill your LED devices and observe what happens.

 

[Rhyno]

He won't, because he's chasing imaginary problems. There's no "filtering" difference between a $.49 Home Depot bargain bin switch versus a $15 Hospital grade switch.

This is in the same vein as "I can feel the wifi" people.

Read further as you might get educated with this thread.

You are not right nor correct with your claim of a "filtering" difference, as there is an electrical radiation that happens with your referenced switches.

You just have to possess the ability and willingness to understand what others have measured prior to your personal knowledge. It is your responsibility to learn before inaccurately piping off.

Have a good day though.

 

[frank001]

A tin foil hat connected to your shoes would fix the problem.

Could be, but I'm not sure anything could fix this guys problem for obvious reasons.

Thanks for the input, but I don't know if it is an outside source. It could be which I was wanting to address the other things that are within my control. If it turns out to be something like you have suggested, I won't be able to control that.

I look forward to your addition.

The first thing I would do is measure from neutral to each hot in your load center.

Then measure from ground to neutral. (should be 0v)

Grab a metal poll and drive it a foot in the ground. If the ground is dry, wet it.
Then measure from the ground in your load center to that rod. It should be close to 0 Vac.

If you get like 10 - 20 Vac or more....start looking for a bad earth ground to your load center.

Do a balance test. Plug in an iron..don't turn it on.
Measure from neut to one of your legs. Turn on the iron....there should be no drop at the load center.
Put the meter on the other leg to neut. Repeat the iron test. If you see the voltage go up on either leg with the iron is turned on, you have a transformer issue.

Do you have any AFCI breakers in your panel?

Do you have access to an Oscope?

This list is too long for any of us to help you with all at once. Pick one item and we will try to help diagnose it.

And we need more precise information on each item. For instance, "a":

a. Data delivery upon partially shielded CAT6 cables.

What is the problem?
When does it happen?
What are the specific conditions when it happens and when it doesn't?

Etc.

I look forward to see why you would think adding a capacitor (to?) will help eliminate problems that doesn't seems to be from power lines. You might be barking at the wrong tree.

What is partially shielded CAT6 cable? Either it is shielded or it isn't. If it is shielded cable that is NOT properly grounded it IS going to introduce interference.

Thanks for the suggestions. I have accomplished a few of what you have suggested, but will do the other things. Hopefully, I will find an answer.

I am unsure if I have AFCI breakers. This sounds like I might have to look at what these have to offer.

I believe that my breakers are called Circle D GFCI breakers that were good common ones in 1976. I have replaced a few of them with purchases from big box hardware stores.

I do not have access to a scope which is why I asked for suggestions earlier in this thread. Since one recommendation, I still have not got one to use.

But I can use my voltmeter to do more testing and scenarios.

Thanks again.

Did you not see nor understand the multiple powerline conductor(s) description that run parallel with the RR tracks and US hwy along with the shake flashlight induction charge theory?.... that are only a few feet away from my home and cross over my supply lines?

You might be correct with the wrong tree assumption, but I have seen this capacitor installation in other industrial installations as I detailed in the OP. This resolution is also listed as a resolution from an earlier posting from a fellow garage journal member.

Time will tell though.

 

[Rhyno]

Your question too seems like it is based from a partial understanding and partial effective reading of the OP. Please go back and read again.

But to save others..... and said within the OP.....my relay of "partially shielded" was accomplished by lifting the DataCables as far away from the AC lines while hanging them from the roof rafters, and also by installing tin backed styrofoam and also partially shielded by Reynold's wrap (tin Foil) at data cable(DC transmissions) and electrical cable(AC transmissions) crossover or cross near points.

Is it clear as mud?

Addition upon edit... there are also a few ungrounded HDMI cables that have multiple layers of shielding and are case grounded together at the devices at either end with the ground going to the electrical system ground. I occasionally see visual interference problems on this device but only upon one camera at a time and not with a predictable pattern or length of time.

You asked and I delivered. I understand your lack of comprehension and appreciate your willingness to still resolve. It seems complicated though.

Multiple problems. listed in the OP.
With a few different timings that vary and are also relayed in the OP.
The specific conditions I have not been able to document.....ie.. weather, temperature, wind, etc.

Capacitors are usually used in power lines to correct the phase lag or lead of a voltage and current in AC (the power factors)..... something to do with industrial power get charge by their Aparent power uses. so what ever the formula they use... the power factor closer to "1" is 100% power... I don't really remember or want to go into the electroma-engineer part of this.. not an expert. But for some one that is into ham radio this is something you should know of.. It have nothing to do with your EMI/RFI...

https://www.allaboutcircuits.com/te...ent/chpt-11/true-reactive-and-apparent-power/


If you do feel the shocks... you might have some sort of straight or transient power going to your ground or the worse... radiations, or EHS (https://pubmed.ncbi.nlm.nih.gov/32289567/)... like I said before if you have something that strong that would have cause you to tingle... better to hire some Scienmatests and lawyer up.. or move. Nothing will shield you from those EMI / RFI that is 250' away and still give you the tingles. Just saying. Might be your home electrical that is leaking to the ground for what ever reasons...

 

[Rhyno]

OPs grammar and syntax feels suspiciously like AI.

Maybe the earlier and repeated "tinfoil hat connected to your shoes" was intended for you and the others with a similar perception/paranoia complex. Even further if you follow his signature, maybe a few circles being ran repeatedly will also assist with the anxiety. I suggest that you run until you find the corner.

Have a good day, though.

Thank you for the addition of PowerFactor possible theory. I have previously looked into this but have not completed the analysis for this and suspect that this too adds towards the other things listed in the OP complaints and shown by my earlier comments of wire length distance from the power panel. From what I have read and been told by others, electrical Resonance can radiate and contribute towards RFI/EMI.

Today and earlier, a few other GJ members have suggested a few moves to further check and diagnose the grounding of my system and Waveform measurement. I hope to accomplish their suggestions soon.

I will read though your links with hopes of finding something to help with the resolve.

In my area, most of the attorneys are overrated, souless, underperforming bad actors who refuse to uphold established law nor to do anything near what is simply christian right. Unfortunately, the religious based education keeps pumping out BAR exam passed return marshmallows.... but this is another and different argument....probably for a different forum.

Yeah, you might be right.

If you go read his previous started threads, OP is using normal grammar and syntax. Then there is a four year gap in his posting history, and now we have this nonsensical thread started where he's using convoluted grammar and syntax.

Who knows, it could be a spammer using a hacked account.

 

[logical]

Yeah, you might be right.

I noticed that. When I see really odd posts I look at history just to see if I've missed some entertainment. The other possibly of course is that we are witnessing the long term effects this kind of interference can have on a brain.

It appears that much of your troubleshooting has inserted ground loops, too many paths to ground and such. Most comm cabling, CAT whatever and coax included are too be grounded to one spot, on one end of the cable - NOT grounding every penetration and cable crossing, tray, hanger and so on.

AC solutions are not DC solutions or ground/bond solutions and vice versa.

Tempest testing in the old days taught us many things.

The solution you need to implement is a Faraday Cage, cost might be out of line with what you hope to solve.

OK, I'll play.

What have you done to rectify this particular problem?

Have you switched cables or connectors or routed them differently or bought better quality cables and installed them? Have you used a different computer to see if that is the problem?

The answers are in the OP with a few supplemented within the addtional replies.

Yes, on all of these questions.

Have you used a different computer to see if that is the problem?

Yes on this too.

Thanks for your efforts.

Thanks for the addition. I have thought about the ground loop theory but do not completely understand the potential.

I agree with you on AC solutions versus DC solutions.

I will have to further evaluate the Tempest testing theory that you have mentioned.

I have implemented an electrical circuit grounded small faraday cage upon the security NVR and it immediately cleaned up most of its problems. Occasionally, one camera at a time will go through a repeated restart/reset process. This camera will display fine, restart and work fine and do it repeatedly again. It will do this for hours that have never timed, nor documented to identify a pattern. It has a Cat6 cable that is the longest length of the entire system, but is much less than the system requirements of 300ft or less.

Are there any Hams in your neighborhood?

Also, if you read the instructions on many electrical devices, they are not guaranteed to be free from interference.
