Technology
The S2 technology utilizes the electrical waveforms measured non-intrusively from the low voltage side of the power infrastructure, eliminating the need for costly sensors, power supplies, and wiring. Patented and proprietary signal processing and interpretation algorithms are at the core of the technology. It comprises elements of multi-resolution and statistical signal processing, adaptive learning systems, statistical decision making and fuzzy logic. The electrical waveforms, both voltages and currents, are measured at the machine switches. They are processed to eliminate the effects of operating and environmental conditions, and then analyzed to provide indicators for long term condition tracking. Adaptive thresholds are computed to flag machines with developing anomalies or faults. The system indicates whether the developing fault is in the motor or in the driven load. The technology has been tested on over 100 different machine failure modes/operating condition combination using staged, accelerated life and field tests.
A partial list of motor faults detectable by the technology includes:
- Bearing degradation,
- Rotor bar/end-ring cracks,
- Mechanical unbalance,
- Eccentricity,
- Misalignment,
- Turn-to-turn shorts, and,
- Neutral-to-ground shorts.
- A similar list of pump faults includes:
- Cavitation,
- Dry running and partial flow,
- Impeller cracks,
- Bearing degradation, and,
- Seal leak & degradation.
