Power quality analysers - Eng-Tips

Make sure you evaluate whichever meter you pick it and ensure you can get the data you want out of a recording. In the past, I used a RPM logger which was supposed to be a great logger but it was a royal pain to find good data in a PQ recording (there were 's of events and most were meaningless) and all I could really get out of it was waveform captures of the event. RPM was purchased by Fluke quite some time ago and the new version of that logger is now a . Fluke still has a number of meters where you they expect you to take basically screen snapshots to record data, so check what that gives you as output data when you capture what you're looking at.

The Elspec appears to be a meter that would record a ton of data if you are looking for that. It sounds like instead of triggering on a system change it just records continually with that listed samples per cycle for up to a year. That could be a good thing or it could just overwhelm you with excess pointless data.

I've used a AEMC Powerpad a few times lately and I thought it was a good meter that was easy to use. I can say it works great to check the present state of equipment to get a recording of the present power conditions. A snapshot of the recorder data gives the currents & voltage data showing waveforms, RMS levels, harmonic spectrum and individual harmonic data plus the power data on each phase. I never really did any logging though so I can't say how well the logging and transient capturing works.

Dislike was perhaps a bit too strong a word.

I'm not hugely keen on the user interface, but I'm a grumpy old sod who likes old-fashioned buttons and knobs. More importantly for me it doesn't adapt well to external CTs which is a absolute pain in the butt when all you have are CTs on the machine and no prospect of using the Fluke probes on the secondaries. The probes use some goofy custom connector instead of a pair of 4mm jacks, probably in the name of safety, or in the name of preventing use of industry-standard probes in order to maximise profit...

On the positives, it's a fifth of the size and weight of the bench instruments, reasonably rugged and arguably better suited to a field testing environment, and it is cheaper than the big bench instruments.

In my opinion the bench instruments are more capable overall, but you pay a premium in both cost and portability. That's a decision weighted by what you'll use it for.

I must say I love my Fluke multimeter and have used little else in 25 years, but since they merged with Philips in the 90's and started dabbling in scopes I've not liked any of their Scopemeter products. I would pick my late 's Tek THS730 over anything Fluke make today. If you like the Scopemeter interface then you might like the analyser: best bet is to get one on loan for evaluation and see how you get along with it.
