That's what I thought too.
I am doing PF testing and harmonics testing with a Fluke 434, and downloaded the new firmware to correct some bugs in it.
On a 480X240/120ct transformer I am monitoring, if you switch from delta to wye on the Fluke, the PF changes from .67 to .94.
I am curious why, they should be the same measurements unless somehow they get measured differently in the meter.
But that makes no sense..
Thanks.
Dnk.....
