Greetings Corey, I do not have experience with the specific devices referenced in the contract language you have cited, but can offer the names of a couple other manufacturers who make power quality (PQ) analyzers and loggers/recorders.
Here are three: Power Monitors, Inc. (PMI), Virginia, USA Radian Research, Inc., Indiana & Mississippi, USA AEMC Instruments (Chauvin Arnoux), New Hampshire, USA These companies produce gear which many utilities and line contractor firms use in their PQ testing programs. I have worked with some of the gear from PMI and Radian Research, but probably not their latest models. If it is unlikely that your company would have an ongoing need for a PQ logger it may consider hiring a local/regional PQ test company/contractor (or appropriately equipped engineering firm) to fulfill this requirement in the contract you have mentioned. They could potentially perform the testing, review the logged data, and prepare a report for less than what a new PQ analyzer logger unit and software would cost your company. If your company does purchase new gear some manufacturers or their regional representative may come out and train/assist/demo the unit with your technician/team. SEI Professional Services may be of help on this issue too. They have members on the RE-wrenches list as well. On larger or complex projects I like the practice of PQ testing and data logging at a project site before the system installation as well as during commissioning activities. The pre-install data can be helpful in seeing potential PQ issues before work begins. The pre-install data can also be used later for comparative purposes if there is any concern or dispute regarding PQ issues recognized post install. Best regards, ----MATT Matthew Sirum P.O.

Devices such as a Candura Power Pro or Power Site can be used to analyze power." Does anyone have experience with either of these devices and can comment on their use? Or else can you recommend a similar device that will fulfill these requirements?
