Yes, That is definitely that part I was missing. From what I was told from others, that wasn't possible. Ok, well that definitely makes more sense.
I guess I don't get HOW that's possible...but maybe that's another discussion.
Purpose - Test VFDs. Put them under test for 1-2 hours before shipping them out to customers.
I think it's smarter to vary the load conditions but I can't make that decision for the customer...just my 2 cents.
Now here's where I still don't get it and please forgive me - I don't understand...
Sorry I was on the road Thursday/Friday...
Anyway, I guess I'm not fully understanding this. The motor they have connected to the grid needs to be over sped before it becomes a generator, right? So if it's running 60HZ off the grid and the other motor/VFD is running at 64HZ, it would...
They only plan on over speeding the motor connected to the VFD to 63 or 64HZ. You can regen power back to the grid without a regen VFD? How can you do that? I guess I don't understand why people would buy a regen VFD if they don't need to?
I'm trying to understand something that I'm being asked to help supply motors for. The customer wants two 600HP motors. One motor to run off their VFD and the other motor to run off the incoming 3 phase power. That part doesn't really seem to be an issue.
They also want to regen the power...
