These circuits are in railroad shelters. Sometimes a man-sized metal box, sometimes a metal hut that can hold a few men, sometimes a wooden structure.
Here is what is confusing me. I "want" to relate the induce EMF to the length of the wires parallel in some specified close proximity to each...
Thank you for that very straight forward explanation and math.
A question about your diagram, what is quantity "b". It looks like it is the distance from the 6AWG wire to the far side of the loop.
You are correct Philip ... the induced emf. The loads, wire gauge, & length vary for other similar projects. This criteria is the immediate.
This type of problem is recurring for me. My approach in the past probably produces correct results but is gross overkill. Time for review of the physics.
These are 2 straight wires parallel for 3 inches. Specifically a 6AWG and 12AWG separated approximately 2 inches. A surge current enters on the 6AWG which has a rising edge of 2500A/us.
This is for a surge device ... I have been working in plain old RF for too long to be certain that I using...
