Yes that is correct. I don't know of a way to check the system. You see during that talk w/ facilities guys part of their problem is that the rods are covered in the slab. Not the best idea I've ever heard but I'm no EE. I even asked if they had megged the rod points and they said that a certain car manufacturers' engineering dept. said to cover it over w/o a test. I don't know what they know.Lancie1 said:I know there are sandy parts of Texas where 3 rods in a loop would not be enough to achieve a 25 ohm path-to-ground.
Identify the noise source. That's what needs a ground.
Yes that is my objective I believe.
Subtract the square wave first, so you can see the noise.
I am not that proficient with the scope to understand what you are describing. Can you elaberate?
Can you scope the line unpowered?
Can you scope the ground?
I will try both of those in about an hour when the crew takes their break. Production.
Lancie1, Mordred, Keithkyll thanks for your help and responses. I will post back with my results.
