Corrections Needed for PV Performance Blind Spots During Commissioning

Solar Industry, July 2014, by James Mokri & Joseph Cunningham.
http://www.solarindustrymag.com/issues/SI1407/FEAT_04_Corrections-Needed-For-PV-Performance-Blind-Spots-During-Commissioning.html

"If a photovoltaic system is commissioned according to industry standards, then it must be performing as expected, right? Not necessarily. PV industry standards for commissioning do not include performance testing.

NEC code and IEC 62446 mention nothing about performance testing. ASTM E2848-11 outlines a method of performance measurement during the commissioning stage, but it is not a complete, consistent, standardized method of measurement and metrics."

Identifying a Guide Bearing Rub Using Vibration Analysis

Hydro Review, May 2014, by Bernard F. Boueri.
http://www.hydroworld.com/articles/hr/print/volume-33/issue-4/cover-story/identifying-a-guide-bearing-rub-using-vibration-analysis.html

"When commissioning a hydro unit, proper use of vibration monitoring can help identify problems such as a rub on the guide bearings. Catching issues early can allow the problem to be fixed quickly, preventing units from operating inefficiently and limiting unplanned outages."
