STATOR CURRENTS IN AC GENERATOR
STATOR CURRENTS IN AC GENERATOR
(OP)
We recently ran an URGE test on a steam turbine generator. We didn't experience any problems, but after reviewing some data, we realized that there is some variation in the stator currents for the different phases. We measured up to about a 3% difference between two of the phases. My question is: Is this a problem? I am not sure if this is typical of steam turbine generators or if this is something to be addressed and researched. Any input appreciated. Thanks!!

System voltage unbalance is another factor that could cause phase unbalance.

We feel confident that our rotor alignment is good. However, we do have a voltage unbalance which is likely causing the problem.
