    VFD Low Load Power Factor

    oz, or anyone else who has used the AFE, what are your thoughts on using the AFE as a power factor correction capacitor for lagging induction motor loads connected across-the-line to the same bus as the AFE, parallel to it? what I would want to do is modify the AFE's power factor during...

    VFD Low Load Power Factor

    Good stuff guys. The powers are pretty small - the generator will be 250 kVA but we don't expect a 250 kW load - more like 180 kW at full load. My question was originally about the power factor of the VFDs, but I think I was asking the wrong question. My question should have been "what is...

    VFD Low Load Power Factor

    I read that thread and it's good. The thing is that I'm concerned with all power factors since I'm trying to optimize a system for a startup procedure. I need to know how much steam to make so I can spin a turbine to turn a generator to supply enough apparent power to run some blowers by a VFD...

    VFD Low Load Power Factor

    Can anyone point me to a reference that can help me estimate power factor of a VFD running a fan load but only slightly loaded? The red book says VFDs have poor power factors at low loads, but that's all the farther they take it.
