oz, thanks for the reply. I'm talking about what the VFD can handle in the electrical system. Specifically, there's a chiller with two 50hp (non-VFD) compressors. during generator operation, when these compressors start the voltage will dip as the generator controls compensate. I wanted to...
I'm running a generator sizing program and I have two VFD's (15 hp and 20 hp). I can select each of these for up to 25% permitted voltage dip (to reduce the size of the generator), but now I'm having trouble finding VFD's with greater than 10% permitted voltage dip. Any suggestions?
Thanks and...
