3-phase power analyzers for low power-factor measurements
3-phase power analyzers for low power-factor measurements
(OP)
I am looking for good quality 3-phase analyzers for measuring power and power factor accurately in a very low pf (0.1 to 0.3 typical) environment (testing a wide range of LV and MV motors on no-load, short-circuit etc.).
Any recommendations/suggestions ?

I highly recommend Voltech's PM3000 analyser. I have used these for about 12 years and while it's no longer their flagship model it is still a damned good instrument. Cost when I last bought one was about 6k GBP, and looking at their website it has only gone up 200 GBP in the four or five years which have passed. I can't comment from experience on the newer PM6000 but on paper it looks excellent.
Spec is on the back page: ht
Voltech in Abingdon, UK used to have some very good technical guys - might be worth a call.

PM3000 ACE sure packs a lot. I will get in touch with them.

Voltech used to extoll the virtues of their instruments in transformer testing where the no-load PF is close to zero lagging. http://w

0.01 pf of trafos on no-load ? Is it a tall claim ?
prc, as a trafo expert, would agree with that voltech statement ?

I wonder how voltech made a claim like that.
