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...

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...

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...

As maintenance and reliability professionals, we know that the life of bearings and other components will be reduced through misalignment. Still, there’s a question: What is the impact associated with misalignment, meeting basic alignment tolerances, and...

Electricity: Other than work performed through connected equipment, it’s invisible and rarely considered until a blackout or other dramatic event occurs. From a reliability perspective, more effort is spent on understanding the greasing of a bearing that would...

Take it or leave it, the discussion of greenhouse-gas (GHG) emissions has been relatively dominant in energy industry circles since the early 1990s. These days, industrial operations look to projects that will reduce energy (which directly impacts the bottom line) and...
