Do a quick search on the accuracy of machine learning (ML), artificial intelligence (AI), or Internet of Things (IoT) predictive maintenance (PdM) to understand what the potential implications are. Most of what you’ll typically find are white papers and other...

In the last two parts of this article (see links below), we used data from a non-commercial data collector on a 10-hp electric motor to explore how MCSA/ESA (Motor Current Signature/Electrical Signature Analysis) spectra are developed. We looked at the way different...

In Part 1 of this 3-part article (May 8, 2022, see link below), we discussed taking a raw data sample and using a simple data-processing technique to make it look like something we might see on a Motor Current Signature Analyzer or Electrical Signal Analyzer (MCSA and...

Over the past few months in The RAM Review, we’ve been waxing philosophically on large-scale electrical issues. Now, let us dive past the basics and get more specific. In particular, let’s get into the programming nitty-gritty of Motor Current Signature Analysis...

Big Data. That definitely was the tipping point. Over many years, starting in the 1970s, concepts around replication of human interactions through computers and the terms “neural network” and “Machine Learning (ML)” were found mostly in...

Prior to the 2000s, discussions about electric power and the grid mainly revolved around reliability and availability. Of course, there was some understanding of issues related to early smart-grid communications and cybersecurity. But it wasn’t until the 21st...

It is 2022, and we are discussing electrification of everything, a transition to all-electric vehicles, the integration of new power sources, and a general change from fossil fuels to alternative energy. Somewhere out there is a fleet of power-generation that powers a...

We’re now back to face-to-face meetings in Washington, DC. The last in-person meetings with legislators and Federal agencies were in 2020. This year, the focus through Business Leaders United, SMRP, and American Clean Power (ACP), was on the JOBS Act, other...

Noise and vibration are measurable losses in the operation of a rotating system, and they can be directly identified in electric motors. As noted in Considering The Direct Energy And Environmental Impact Of Misalignment | THE RAM REVIEW, there are definitive energy...

One message floating around the physical-asset management community is that “reliability and maintenance are an income.” It resonates deeply given the fact everyone wants to feel that whatever we do is important to our organizations. Maintenance is clearly...
