Thanks!
I'm doing some preliminary motor starting studies (fatal flaw analysis) for a centrifugal gas compressor addition. I'm using SKM for the modelling. We're proposing using a low inrush 12.5 kV synchronous motor. The methodology proposed (by my client) to start the motor and control utility flicker...
I am engaged with several clients who have large numbers (in some instances several hundred)of small VFD's (typically 20 - 40 hp) of similar inexpensive 6 pulse drives installed over a number of years. These are fed from either 12.5 kV or 34.5 kV overhead and underground electrical distribution...
