I never thought about imbalance in those terms. I guess I was looking at it from a plant electrician's point of view. If the device indicates it protects for motor phase imbalance in the range of 40-60% and a RMS clamp on is all you have it would be have to be magnitude. I.e...
To: PeterB. Isn't that like shorting all three outputs of the powerstat together? The device under test is a pass through device, like a contactor. Won't I blow line fuses or something worse?
To: Electricpete, the device uses current transformers to sense/measure current.
To: Busbar, I have...
To EPete: I don't think I'mI daring enough to try the liquid approach... Thanks anyway

Thanks for the response. I believe the power system is a 480V wye. I've measured each phase to ground and found 277V. I have many different test motors available: 5 to 30 hp. I originally wanted...
Does anyone know how I can easily create a phase current imbalance on a 3-phase AC motor? I am testing a product that claims to protect for motor current imbalances and I'd like to see the point (how much of an imbalance) at which the protection works. I would like to be able to create current...
