Power/Power Quality Metering
Power/Power Quality Metering
(OP)
Hello,
We are currently spec'ing out meters for different locations on our site and I started comparing Power Quality meters on the market today. I am currently looking at the Square D ION7650, Eaton Powerxpert 8000, Fluke 1750. The question is, does anyone out there have any good references/papers/web site's that compare these different types (sampling rate, memeory, communications...) of meters and other that are available today? Does anyone out there used these meters and like one better than others and why?
Thanks,
Jerry

RE: Power/Power Quality Metering
Myself, and the end users really liked the large custom screens available and the easy navigation via the soft keys. We were primarily concerned with energy metering.
Granted, I had a 3 phase relay test set available and could test the various custom functions I desired.
The Ethernet and Modbus communications worked as expected on the first go.
I can't speak directly for the other two units, but I would assume similar from similar platforms.
RE: Power/Power Quality Metering
If the application is for just in-house metering and PQ measurements, I suspect there are a lot of meters that will meet your needs.
Might also have a look at Electro Industries offerings (Shark meter among others).
Also the SEL-734 is a very capable product and much less expensive than the ION 7650. The display is not nearly as nice as the ION meter, though
RE: Power/Power Quality Metering
The meter did not require much in terms of presets. If a CT was connected incorrectly, this could be resolved via SW later.
The reports were quite comprehensive and basically created themselves. For PQ issues, again not having to set up much in terms of thresholds was very impressive at the time. I had used BMI and Dranetz previously and had nightmares of no data / too much data.
With that said, it seems like you are looking for a permanent installation. The Fluke 1750 may not be suited for your needs.
As DPC said, SEL products are very good. The display is small, but if you are using communications, this can be overcome. If you ever imagine doing any automation / control, the SEL would be very simple to configure and apply. The new SEL Meter, the SEL 735, has a listed base cost of $1500, per website. As stated many times, by many members here, SEL has excellent support and product quality.
I would narrow my choices to the ION and SEL devices. Consider that the ION basically has an HMI built in, the SEL doesn't (small limited display). If you have intentions of using the meters to communicate and analyze from an upstream PC, I would choose SEL. If you want something that is easy for maintenance folks to use without connecting to a laptop, consider ION. ION support is based out of Canada.
RE: Power/Power Quality Metering
You can check also SATEC devices. like to EM720 or EM920.
A new Siemens line, sorry Im not remmeber types
RE: Power/Power Quality Metering
You really didn't state what you wanted the meters to do.
Accuenergy @ www.accuenergy.com makes some decent and low cost power meters such as the Acuvim IIR (revenue rated) or Acuvim-X. They could be suitable but then maybe that's not what you want at all.
Another option is the Tyco meters, such as a Integra 1530. Similar to the Accuenergy meters but a higher price.
