Keeping up to date with many fields of study
Just got this in the mail recently. In order to understand criticality rankings, its good to get a good grasp on Reliability as a whole. In the next couple of years I need to have a strong base on all of these fields: 1. Thermography 2. Vibration 3. Ultrasound (All
Thermography training at Rockwell
Today we had a training session on thermography. The most important part of the session was the hands-on. Once we got started, the first panel we opened had a thermal anomaly. Before the images above we actually measured 164degC. This is why Proactive Maintenance principles need to be applied
Rockwell Pump Room 9/12/2025
We were taken the pump room for the first time, 2nd floor. Engr. Jim told me about these 4 pumps. It seems like there are pressure issues due to failure of some components. The tenants upstairs experience a drop in water pressure as a result. He told me the right
Finding a leak on a Chiller System 9.12.2025
The Rockwell manager Jim mentioned in a meeting that two of their chiller systems (2 & 3) have experienced leaks. This is after I presented to their management our Condition based monitoring activities in the facility. Chillers usually don't need to refill R134 for a decade. But 2
Solar Projects and Energy Auditing
July 15, 2025 Will have a zoom call with La Sagesse, Rehab Center for their PV solar system. Propose a 40kW system. This is has been in the works since 2023. Funding is an issue. The Sisters had to fund raise. The Church has decided to fund the rest. It&
Rockwell Motor and Pump Inspections
On June 5, 2025 conducted a ultrasound and vibration inspection on all the available motors and pumps. Looking at the data was very interesting, full of sound and vibration. Both provide a TWF and FFT, but the point that these two data sets bifurcate is the fault frequency signature. Ultrasound
Ultrasound and Thermographic inspection of Rockwell Power Plant
I'm not making this post to report a finding or realization. It is to just note that I completed a partial inspection of the Rockwell Power Plant chiller system. I have inspected Chiller 2, 3, 4, and 6. I only inspected those motors and pumps and did not
Finally received this book
I ordered this book November 2024 and it finally arrived yesterday. How it took 6-7 months to get from Canada to the Philippines is beyond me. But it doesn't surprise me. I was, however, surprised and overjoyed for receiving it when I thought I got scammed out
Gerry's Grill Pampanga
May 29, 2025 I had a pretty interesting day today inspecting a Gerry's Grill. There were two learnings. One is about circuit breakers. And the second was about a replacement of an entire exhaust fan system due to a circuit breaker, which is a related incident to my
Experiment on Spot Size Ratio and calculations
I've done this experiment a couple of times but didn't systematically record numbers. Spot Size Ratio is something that is thrown around but most thermographers don't know how to calculate it, let alone know the formula. Here are the items I used for this
Ground Faults on a Solar PV system
I received a notification from an engineer on Linkedin, Kevin John Esperila, on a issue with ground faults in his Commercial PV System. Ground faults can be a common issue for solar PV systems, but tracking them can be difficult. To find a ground fault you would first open the
