Power Quality Analysers
Power Quality Analysers
(OP)
My employer is a distributor of electrical components (circuit breakers etc), enclosures and switchboards.
We are considering the purchase of a Power Quality Analyser set such as the Fluke 433, Amprobe DM-4 etc, for use in tracking down problems such as nuisance-tripping circuit-breakers and the like. We think that the latest-generation of this type of instrument, with transient capture capability, should be very helpful.
Can I ask for advice and recommendations as to what models of PQA are being used, how well they perform, and any pitfalls to beware of?
Thanks

We have a Voltech PM3000 which is quite an old design by modern standards and it lacks the LCD display of more recent models. Nonetheless it is a very accurate and versatile instrument which I find very valuable when troubleshooting. One of the best features is the huge flexibility available by choosing external VTs and CTs or Hall / Rogowski probes so it is possible to make precision measurements at pretty much any power level.
Voltech have introduced some other instruments since our purchase which have nicer user interfaces, as have Yokogawa. The best recommendation I can give the PM3000 would be: if it broke down tomorrow, I would buy another one to replace it (unless I could get the newer PM6000!)
