Does anyone know of a good resource for sizing a field discharge resistor for a 1000hp, 2.2kV synchronous motor? It's 100+ years old so manufacturers data is non-existant. I've found some references of 3x - 6x the field resistance, but I have nothing to back this up. Any suggestions?
You'd be right about that!
I'm just looking into the feasibility of actually designing and manufacturing parts. I've got a family connection in a plastic manufacturing plant and I'm trying to visualize how this could work.
Thanks for the explanation. That definitely clears things up.
I'm not sure if this is the right forum but here goes...
I've always wondered how aftermarket motorcycle parts manufacturers design products when there are a large amount of different brands and models.
For example, if I wanted to design a series of parts that would fit a specific type of...
Is there any way for ETAP to consider different fault contribution times from other sources, even if the faulted generator bus is fixed at 2 second FCT?
The problem is that I need to declare the fault clearing time as it is on the generator side of the breaker, but ETAP seems to include...
The generator in questions is 4.5MW at 4.16kV. The AVR is bus fed.
The study is being done in ETAP 12. I can run the analysis using the integrated decrement curve mentioned by DCP to calculated the fault current. My main concern is the accuracy of the decrement curve. You mentioned that it took...
Hi all,
When conducting an arc flash study involving synchronous generators, it's easy enough to determine the fault clearing time on the load side of the breaker, but for a fault on the line or generator terminal side, how would one determine the fault clearing time for arc flash purposes?
I...
