Online monitoring, portable inspection, core sensing, and a fusion unit in development — a complete power olfaction portfolio
Power Olfaction: Three Questions
What it is, how it differs from TEV/UHF, and how much earlier it provides warnings
What is power olfaction?
Gas sensor arrays detect 7 types of fault gases (CO, CO2, H2, O3, NOx, SO2, hydrocarbons) emitted during early-stage degradation, converting chemical signals into assessments of fault type, location, and trend.
How does it differ from TEV, UHF, or AE detection?
In 6kV–20kV step-voltage tests, AI olfaction alarms detect defects at their earliest onset, whereas acoustic-electrical methods require higher thresholds to overcome site noise. The two approaches are complementary.
How much earlier can it alert?
The window transitions from visible temperature rise or discharge to the trace-gas onset stage. The exact lead time depends on defect type, ventilation, and load, as assessed via CFD placement.

Roadmap
In Development
Extending Olfactory Power into Multi-Physics Fusion Monitoring
Chemical + Acoustic-Electric Sensing in a Single Unit
In DevelopmentPower Olfaction Fusion Monitoring Unit (In Development)
Integrates an olfaction sensor with AE (ultrasonic), TEV (transient earth voltage), and UHF (ultra-high frequency) in a single unit. One device handles both chemical and acoustic-electric sensing for broader scenario coverage. Olfaction and acoustic-electric detection work together, fusing data to monitor PD degradation trends across the entire process.
- Chemical Sensing
- Power olfactory sensor (multi-channel characteristic gas detection)
- Acoustic-Electric Sensing
- AE (ultrasonic) + TEV (transient earth voltage) + UHF (ultra-high frequency)
- Fusion Approach
- Co-located multi-physics acquisition with mutual corroboration
- Status
- Under development, expanding to more scenarios
The fusion unit extends the HOVIK multi-physics cross-validation approach by correlating chemical signals with acoustic-electric signals on a shared timeline.
