What is the impact of an electrical reliability program? Or even the application of a precision maintenance program Overall, the transition to a planned maintenance program from a reactive program has been identified by the US Department of Energy (US DOE) Industrial Assessment Centers (IAC) as having at least 14% improvement of all energy consumption…
It is established that neutral and ground harmonic content will load transformers and systems. Prior work has been limited as to the direct relationship of this additional loading on power consumption for a facility. Over the past 24 months applied research has been performed on the measured impact of neutral and ground harmonics and energy…
A reading of the new book on Electrical and Current Signature Analysis by MotorDoc LLC which is planned for release in the second half of October, 2022.
Volume 3 of the US Department of Energy’s “US industrial and Commercial Motor System Market Assessment” was released on July, 2022. The study reviews the energy performance improvement opportunities for the installed base of commercial and industrial motor systems in the United States. It is noted in the report that electric motors and related systems…
Media bias is not only found related to politics and public policy, but also how we perceive the reliability and maintenance community. From advertising dollars and marketing being presented as technical articles and information to the idea that ‘digital transformation’ solves everything, or that infrared is a complete electrical reliability program. As noted in my…
When dealing with statistical analysis and probabilities its often the missing information that can be an issue. This can result in bias when working in areas such as reliability, data science and machine learning that result in incorrect solutions. We’ve seen that in such things as the percentage of type of motor failures, faulty IoT…

A common question we receive is: ‘what is the impact of voltage unbalance on temperature?’ With incoming power to facilities having challenges in many parts of the United States (and elsewhere) from aging grid and the rapid application of power electronics, this becomes a significant issue. Voltage unbalance is the variation from the average voltage…
As I just mentioned to a friend – I seem to be waxing philosophical this past weekend as I complete reading “Wizard: The Life and Times of Nikola Tesla, Biography of a Genius,” by Marc J Seifer. I would not have tripped over this and several other excellent texts had I not started returning to…
Following is the code used to develop the script bringing the details developed in Parts I-VI together for classification and RUL/TTFE outputs in the Part VII article: (article to be posted by September 19, 2021. *Note: The code in this article is for demonstration purposes only and is not meant for real-world applications of this…
