LV distribution panels: three anomalies caught before the red threshold
Three-phase busbar junction monitoring in low-voltage distribution panels.
- 3Anomalies caught before red (5 yrs)
- 12Sensors per panel
- $800KDowntime per event, approx.
The problem
Across hundreds of factories, the low-voltage distribution panels in the electrical room look identical: rows of breakers, busbars, and T-junctions where three phases come together — common failure hot spots. Most operators inspect them with a thermal camera once a year, under shutdown, which means anything that goes wrong in the 364 days between inspections is invisible until something burns or trips.
What was installed
Thermalpas sensors were bonded at the R/S/T phase junctions inside each panel — typically a dozen per panel — streaming 24/7. A two-level threshold applies: yellow above 70°C, red above 90°C. Maintenance works from a wallboard that is almost always green; when a tile turns yellow, they go and look.
The outcome
A typical factory deploys 12 sensors. Over five years, across these sites, anomalies were caught before the red threshold three times, each avoiding roughly a day of downtime valued at about $800K. The first event alone recovered the deployment cost.
