@cianfa72, while that's true, you really don't need to worry about where the contribution becomes negligible since the grounding... -
cianfa72 replied to the thread Earth ground resistance measurement.Perhaps I was unclear, take an hemispherical grounding rod/electrode of radius ##r_0## driven into Earth. At a distance ##R## from the...

cianfa72 reacted to anorlunda's post in the thread Earth grounded, where does the current flow? with
Like.
For the purposes of simple circuit analysis, the ground does nothing at all. You can leave it out and nothing changes. For the... -
cianfa72 replied to the thread Earth ground resistance measurement.Ok, so to simplify the math one can assume that the "soil hemispherical shell of radius R equivalent resistor" has two terminals or...
-
"Semi-spherical"? No good can come from a word that is a misbegotten hybrid of two languages, Latin and Greek. Semicircle and hemisphere...
-
cianfa72 replied to the thread Earth ground resistance measurement.Sorry, I was sloppy in describing my question. Consider the following TT power distribution system diagram. ##R_n## is the ground...

Starting from this Fall of potential method, earth ground resistance measurement of a ground electrode E driven into the ground can be...

cianfa72 replied to the thread Ground loop on electronic audio systems.Sorry, do you mean power outlet's Line (L) points could represent different phases of the three-phase electrical power distribution...
-
cianfa72 replied to the thread Ground loop on electronic audio systems.Basically your point is as follows: L1 accounts for the self-inductance of the coax cable's center conductor, i.e. it accounts for the...
-
cianfa72 replied to the thread Ground loop on electronic audio systems.Added capacitor C3. Now from this schematic, one should be able to analyze the impact of ground loop on the single-ended transmission...

cianfa72 replied to the thread Ground loop on electronic audio systems.With reference to the diagram in the OP, I came with the following schematic L1, L2, L3 and L4 coils account for the inductance of the...

-
cianfa72 replied to the thread Ground loop on electronic audio systems.Yes, of course. That was just a theoretical assumption just to understand things... Sorry, if you were to draw a diagram, where would...
-
cianfa72 replied to the thread Ground loop on electronic audio systems.By the way, w.r.t. the diagram in the OP, suppose the coax cable's external shield between C1 and C2 equipments had zero resistance...
-
cianfa72 replied to the thread Ground loop on electronic audio systems.Ok. You mean the PE wire/cable could be disconnected from the local earthing system or could have high resistance w.r.t. local...
-
cianfa72 replied to the thread Ground loop on electronic audio systems.Just to be sure: PE is just the wire/cable that is supposed to be connected to the Neutral wire (N) and/or to the local/domestic...
