Can anyone detail the parallelling of multiple idlers. I've looked at the possible topologies of such a system (at least as I seem to see it) and I am getting a real headache.
In a multiple parallel system, all but one motor should be self-starting since there is already 3-phase available on the bus. However, trying to figure out how to connect it has me really confused.
At first glance it seems that all that is necessary would be to connect the 3 phase lines (A,B,C) from the motor to the A,B, and C lines of the bus (with a disconnect between the motor and bus to isolate each additional idler. When that switch is closed, the motor would start just like any 3-phase motor should when supplied with proper 3-phase current. But then, after it's started, would it then feed the bus and increase to total system capacity?
This seems just TOO simple and in my attempts to overcomplicate it I seem to get into 'front' feeding and 'back' feeding and current coming and going through the same wire.
The more I learn about this subject the less I know. I wish I had taken a course in alternating current theory back in those dim days past when I was a physics major. Can anyone suggest a good (EASY...I'm a long time past calculus) text that would be a practical introduction to the subject.
I sure would appreciate it if someone would give me a practical discription of how such a parallel system would be configured. (Would love to see a diagram).
