Where it is used
Typical tasks
- Wind turbines
- Diesel generator sets
- Gas turbines
- Hydro generators
- Steam turbines
Description
Artesis e-PCM (Electronic Plant Condition Monitoring) is a specialised system for monitoring generators and their prime movers. It uses patented sensorless technology — the generator itself becomes a complex sensor for faults in the turbine, engine or driven train.
Key features
Sensorless generator monitoring
- Generator as sensor — analyses generator output signals
- No extra sensors on the prime mover
- Real-time online monitoring 24/7
- AI algorithms — automatic fault classification
Applications
Wind turbines
- Main shaft bearings
- Generator bearings
- Gearbox (where fitted)
- Rotor imbalance
- Blade-related effects (indirect)
Diesel generators
- Engine mechanical faults
- Generator electrical issues
- Fuel system problems
- Cooling fan condition
Gas and steam turbines
- Rotor imbalance and misalignment
- Bearing wear and lubrication
- Coupling to generator
- Overall vibration-related stress
Detectable faults
Prime-mover mechanical faults
| Fault | Early warning |
|---|---|
| Rotor imbalance | 2–4 weeks |
| Misalignment | 1–3 weeks |
| Bearing wear | 4–8 weeks |
| Mechanical looseness | 1–2 weeks |
| Gearbox defects | 2–6 weeks |
Generator electrical faults
- Stator winding looseness or shorts
- Rotor winding defects
- Load asymmetry
- Power-quality harmonics

Wind energy detail
Monitored components
- Main shaft — bearings, rotor balance, coupling
- Generator — bearings, windings, air gap
- Auxiliary systems — pitch hydraulics pumps
Benefits for wind farms
- No sensors in the nacelle for prime-mover faults
- Fewer climbs and maintenance visits
- Early warning → planned instead of emergency stops
- Remote monitoring from control centre
Backup power (diesel gensets)
Monitored components
- Engine — bearings, fuel, cooling fan
- Generator — rotor, stator, excitation, AVR
Benefits
- Assured readiness when grid fails
- Automatic health checks during test runs
- Prevents costly critical-backup failures
Software
Artesis Cloud
- Fleet dashboard for all generators
- Trend analysis and alarms
- Email / SMS notifications
- Remote access and management reports
Control-system integration
- SCADA alarm levels
- PLC trip signals on critical faults
- DCS for large power plants
Advantages vs traditional vibration
| Feature | Traditional vibration | e-PCM |
|---|---|---|
| Rotor sensors | Required | Not required |
| Nacelle access | Frequent | Reduced |
| Analog wiring | Long runs | Digital only |
| Installation cost | High | Lower |
| Generator electrical faults | Partial | Full coverage |
Wind-farm ROI
- Lower OPEX — fewer technician visits
- Higher availability — less unplanned downtime
- Condition-based maintenance scheduling
- Extended asset life
- Improved safety — less work at height
Case example — wind farm
Site: 20 × 2.5 MW turbines
Challenge: High maintenance cost, bearing-related trips, expensive nacelle access
Solution: e-PCM on all turbines + central SCADA + cloud monitoring
Results:
| Metric | Before | After |
|---|---|---|
| Unplanned stops | 8/year | 1/year |
| Maintenance visits | 40/year | 20/year |
| Failure cost | $200K/year | $25K/year |
| Availability | 94% | 98.5% |
| ROI | — | 14 months |
