Ground Loops: Grounding Series (Part 6)

- What are Ground Loops?
- Ground loops occur when two different points in an electrical circuit are intended to be at the same potential, but in fact, are at different electrical potential. Current will flow between whatever conductors are available in the circuit
- Unintended current flow is what causes issues in electrical systems, like electrical “noise”, or interference in many different signals that are being transmitted
How to Avoid Ground Loops:
- Make sure that all circuits, especially signal circuits, are referenced to one point as ground
- Remove grounding connections at the various pieces of equipment through the system
- If you remove these types of connections, make sure to implement proper grounding techniques to make sure they still have a path to ground through a single point

Out if all the videos on youtube, finally, a plain language straight forward explanation. Thank you. Incredible how simple, but how much crap people add to videos explaining it
Thanks for the support!
Thank you for this simple explanation. The more I learn about grounding and bonding, the more I realize I don't know.
You are so welcome!
@@RSPSupply When I was in a military E&I (comm construction unit), I helped install a ground array, with 10 or more 12 foot copper rods placed in a circle, pointed toward the center, in the bottom of a deep pit. We used One-shots to bond all the rods together with 2awg solid copper wire, then bury all of it but the single connector point. I did not help design the array, but I could see that the engineer(s) that devised it did so considering a list of factors. I thought it was intriguing, very interesting.
Excellent. Liked and subscribed :)
It is certainly helpful 🎉
Do you have book on Earthing subject in pdf format? Very useful knowledge. 👍🏻
Great video! It was very clear and information was efficiently communicated.
I have a question, though. At 1:56, when you say it is not uncommon for there to be two grounds in a high voltage and frequency application, is this because noise and signal "cleanliness" aren't a concern? Or is this an application where ground loops are actually desired? I didn't understand why a ground loop is common in these situations.
This concept of ground loops is making my head hurt. Electrical code REQUIRES two grounding rods if impedance is above 25ohms is my understanding. Does this not create a giant ground loop that is unavoidable? Not an electrician or anything remotely close but have some sensitive equipment for signal interference and am trying to figure this all out.
Electrical ignorant here: Grounding everything to the same ground means using just one socket for all equipment? Thanks!
That is correct. Normally in an electrical cabinet all the equipment's are bonded to a common ground bus.
Can it appear in new speakers also
I think so
👍👍👍👍👍
Video Starts 1:00
terrible explanation
....In your opinion...
@@chiselcheswick5673 that's right, duhh
