The current flows back to the source through the ground; what is this distance? !
Thread Content
In the event of a leakage, current flows back to the power source through the ground. How far away from the current source must the leakage point be for current to flow back? Is it infinitely far, or is there a certain distance requirement? !
Studying textbooks mechanically – charge, current, grounding protection; I’ve been researching this grounding issue for months now
Non-professionals. It’s normal to spend a few months researching from scratch, right?
There’s no need to take liberal arts students seriously:lol:lol:lol
Go home and read some books, old man.
Sure, you can imagine the Earth as an iron ball
Oh, our Earth has quite good electrical conductivity, haha. .
But the distance is large, so the resistance is high. . .
As for the distance over which the short-circuit current flows back into the ground after relative grounding, it depends on the location of the substation whose neutral point is grounded. There used to be a specialized course called \"Power Supply and Distribution Engineering,\" and I only remember a little about it now; however, there are many teaching videos for this course from various universities available on Bilibili. You can give it a search: lol:lol
