310 to 400 amps. Maybe 450 at the most. Actual service might be 4000 amps. POCO spec conductor based on the actual load to be served. They know most NEC calculated services don't go to 80% of the rating. Some resi 200 amp services don't go above 40 amps. Hence why #8 AL might be feeing it.It's fed with 2 paralleled 3/0 AL SEU. That's 310A in the NEC. What would the service size be according to poco?
CTs are kinda the same way, they will push current regardless of voltage, but only up to the point of core saturation. This is where the voltage is high enough that the iron core cannot hold any more magnetism, so it sort of chops off the top of the sine wave and results in a lower output on the secondary.I wish this thread had a better name as this is actually a very interesting topic.
On line drawing practice problems we have often worked with constant current sources which will source nearly infinite voltage to continue providing a set current.
These CT's appear to be the closest non-digital real life approximations.
