Hey guys,
I am facing an issue with clamp meters, to resolve which I need a little bit of assistance.
I had installed a 30 KW motor which belongs to air compressor and post its installation when I checked its current on all three phases (on load) I was surprised since it showed huge imbalance (72, 84, 75) and was seen to be on the higher side.I checked mechanical side but everything seemed to be fine.
Moreover , the motor wasnt getting hot and nor was the overload relay getting actuated. This got me thinking as to whether the motor is actually drawing such high imbalance currents.
I replaced my meter with another one but showed the same results...Now I am confused as to what to conclude.
Could this be a meter issue or a wrong measurement technique?
Pls help
