Technical Advantages
Gas-sensing-based ultra-early warning technology that exposes subtle or intermittent partial discharge (PD) and overheating defects in medium-to-high voltage systems.
Principles of AI-Powered Electrical Olfactory Sensing Technology
Early defects in MV/HV systems release characteristic gases. Howick AI olfactory monitoring detects these subtle chemical signals before faults escalate into serious issues.

Characteristic Gas

Different fault types and stages exhibit unique gas composition and concentration patterns. HOVIK leverages multi-gas composite detection and AI-driven modeling to translate gas signals into fault classification, location identification, and trend prediction—shifting maintenance from reactive repair to proactive warning.
3-in-1 Detection
One system covers three major hazards in power supply and distribution equipment.
Insulation Overheating
Insulating materials decompose under heat to produce CO, CO₂, and alkanes; odor detection occurs before significant temperature rise.
Partial Discharge
Partial discharge generates characteristic gases such as O₃ and NOx, providing gas-dimension evidence for discharge hazards.
Environmental contamination
Monitor pollution and corrosive gas in the distribution space to assess equipment environmental risks.

Cross-validation for more reliable conclusions
Cross-validated with industry-standard methods including HOVIK, Prysmian's PRY-CAM (partial discharge detection), and Fluke infrared thermography (thermal imaging). Olfactory gas signals are correlated with partial discharge and thermal measurements; multi-physics data collectively supports alarm conclusions, reducing false positives and missed detections.

Evidence
Dramatic Advancement of the Early-Warning Window
Laboratory simulation: Controlled step-voltage test (6 kV → 20 kV) replaying insulation degradation in accelerated time, not live field data.
The earlier and weaker the defect, the greater olfaction's lead; this lead varies by condition, and this test is just one example.
Open full demoCFD simulation with data-driven point placement
For diverse spaces such as switchgear rooms, cable trenches, and tunnels, HOVIK uses CFD (Computational Fluid Dynamics) simulations to model fault gas dispersion paths and accumulation zones. This enables scientifically optimized sensor placement and quantity, ensuring every monitoring point delivers maximum detection performance.
