>Your 237 loops will be affected by ground fault current flowing through the conduit. Not that it will cancel out the total XL of the loops, but it will have some ability to reduce a field.
Okay, so whether the EGC is fairly parallel to the other conductors is not terribly important, right?
And if the fault current returns via a totally different path, then the loops may act as chokes and you mentioned how it could be calculated. Would you care to throw in some hard numbers as examples, like how many 2" loops to limit 100 amps or something?
>Back to the Q:
There was a request to keep "these conversations in a format that us uneducated and less knowledgeable can follow"...
>There's also factors on which direction the magnetic fields cross
So let's assume that they don't cross during a fault and they all cross during during operation.
>A few last things would be the diameter of the coil,
1 or 2"
>permeability of the core
air
>layer depth
Assume outside of pratical influence.
>trueness
perfect
>integrity of the coil
maximum
>These factors will be used to determine the Inductance of the coil
Okay, thank you. We're waiting.
>the motor will be contributing I during a fault
The fault occurred when the motor was being energized for the first time. It was not rotating and did not budge.
>Anyone come up with anything regarding the coiled wire around the Rigid Nipple, with the DC current flowing in another coil thingee??
No, but since we're trying to have fun, I'll venture that you just had me build the primary winding (AC) for a transformer whose core is the DC electromagnet. When I get near to the magnetic field, I become the secondary coil.
