George:
After mulling over this question over night I think I can phrase it better.
Here is the scenario, a 15 amp circuit, 120 volts running at 80%, ie 12 amps, been like that forever, in other words it has a state of equilibrium. Suddenly there is a ground-fault, a bolted fault to ground, How doesnt matter, but now it see a fault.
My question is this what happens to the impedance, the reactance of the circuit does it change, or does it stay constant, and the R of the impedance does its value change, The magnetic field generated by the fault how does that affect the performance of the circuit, and what does the breaker see ? I found one book covering part of it but when it got to double-integrals, and I havent done that in 33 years, I was at a decided disadvantage.
Business has slowed down so this is how I been spending some of my free time.
Any help would be appreciated
Thanks again
