When the lights come on, the water flows, or your home stays warm on a cold winter night, there’s an entire world of planning, design, and engineering that made it possible. Most people never think about it – and that’s exactly how it should be. But behind every power line, substation, and distribution network is […]

Mesa Associates Expands UAS Capabilities with FAA-Approved BVLOS Operations At Mesa Associates, we’ve never been content with doing things the way they’ve always been done. That’s why we’re proud to highlight one of the most significant advancements in our service offerings: our FAA-approved Beyond Visual Line of Sight (BVLOS) drone operations. What Is BVLOS and Why Does It Matter? Traditional drone operations require a pilot

The U.S. electrical grid is at a critical juncture, and for utility providers, the challenge is no longer just maintenance – it is transformation. After decades of serving as the backbone of national growth, the existing infrastructure now faces a perfect storm of aging components, shifting generation sources, and unprecedented demand. Over 70% of the

In an increasingly virtual world, it is easy to assume strong client relationships can be built entirely through screens. But in engineering driven environments, presence still matters. When project teams spend time together on site, they gain something no status call can fully provide…which is context. You see how designs are interpreted in real time,

In November 2023, an Alert was raised by the Anomaly Detection Engine (ADE) on the Air Cooler Output RTD Average (calculated) tag. The second contributing factor was the Cooling Water Output RTD tag, the third was Ambient Temperature, the fourth was Turbine Guide Bearing Temperature, and finally, the vibration on the Guide Bearing. When cooling

The Health Score (HS) for one hydropower generator was deteriorating over time. In April 2023, the HS reached a low of 88%. After a maintenance event correction, the HS was back up to the historically normal level of 95%. In addition to the vibration trends returning to normal levels, the Health Score also returned to

In the previous posts, we saw the vibration increase that was associated with anomaly generation. We also saw the Alerts List with their Contributing Factors. This post reveals the scatterplots associated with the contributing factors, where the training data on the CF are shown in green, and the deviations are shown in red. Clearly, there

Vibration data from the Alert generated on March 4, 2023, shows the initiation of the defect, shown in the green box below. The vibration anomaly increased the amplitude on one of the vibration probes. For this machine, amplitudes below 6 Mils (0.006 inches displacement, peak-to-peak) are considered good. The Acceptable amplitude region is from 6

The Anomaly Detection Engine (ADE) feeds its results to the Apparent Cause Engine (ACE), and based on factors that may include a Failure Modes and Effects Analysis (FMEA), Action Recommendations are generated. Limiting the ACE with FMEA increases the probability of an accurate diagnosis by the ACE. Remember, these are specifically built, intentional outputs for
