Transformer Fault Detection
Oktogrid
- Danish company to do almost exactly what we currently do.
- magnetometer; 3-axis vibration analyzer; ultrasonic mic; transformer temperature
- freq; harmonics; load profile; early fault detection of core, winding, and structure; transformer capacity (IEEE model based on temperature); load forecast; identifying asset lifespan (?)
- Raised €3M in December 2022 (latest round)
- 8 employees, $80k/yr salary
- 2023 annual audit by KPMG
- $200k gross profit (revenue minus cost of goods)
- $650k/yr operating costs
- Selling product as ABB Ability® (page with leaflets)
- Oktogrid customer references
- Outage report example
- Finland customer success story
Magnefy
- American version of Oktogrid
- previous cohort of LabStart
- raised $1.5M in a pre-seed round
- don't think they have any customers yet, hence pre-seed
- supposedly utilizing a high-freq magnetometer, but it looks like their product barely relies on that
Acoustic Emissions Analysis
Vailen
German acoustic emissions company
Waveform-based analysis, such as FFT, wavelet transform, enhanced feature extraction and pattern recognition provides additional information about, e.g. source mechanisms, damage evaluation or wave propagation.
Neuron Soundware
AI-driven acoustic monitoring with easy-to-deploy sensors. Strong in logging, cloud analysis, and real-time alerts for any asset type.
Nanoprecise
Wireless IoT solution, acoustic plus vibration plus environment sensing. Rapid installation (up in days), strong in hazardous industries, provides Remaining Useful Life predictions.

Vibration Analysis
Fluke
Fluke 810 is the preferred tool, and it costs ~$15k/unit. In addition, it requires trained, manual use on the machines, taking measurements that attach to the machine in multiple locations (after inputting into the Fluke 810 the design of the system). The Fluke 810 gives you a diagnosis assessment for different bearings, which is a good offering. It has 800 lines of FFT resolution, which means if you are sampling at 40 kHz, your resolution is 50 Hz.
Fluke 805 is a small meter that looks like a pen, but they emphatically declare that it is not. It is designed for go/no-go measurements. It has 100 Hz frequency resolution, which is not enough for detailed analysis, and does not provide any way to store the data for later analysis.

Tractian does not appear to do the analysis for you — it looks like they give you the tools to do it yourself.
Fracttal
Triaxial vibration sensor samples at 3.2 kHz, which means it can only detect frequencies up to 1.6 kHz, which is low.
