Generator field monitoring
Cutsforth™ has combined Premium Shaft Ground Monitoring and Rotor Flux Monitoring systems into one powerful Generator Field Monitoring system. By combining the functionality into a single platform, customers can achieve the benefits of both systems in one program integrated into InsightCM™ for better trend data and easier system management:
- Allows for Condition Based Maintenance
- Can extend time between maintenance events
- Fewer forced outages
- Reduces operating costs
- Eliminates annual outsource expenses
- Predicts conditions that can lead to failures
- Plants own and control their own data
- The system passes all data to the InsightCM™ data platform
Premium Shaft Ground Monitoring:
Cutsforth™ Premium Monitoring measures shaft voltage and current, while offering waveform capture and multi – feature alarm conditions. The system utilizes Cutsforth™ patented braided copper ropes for best in class grounding and data collection to detect:
- Poor Shaft Contact
- Bearing Failure
- Stator Insulation Failure
- Exciter Insulation Failure
- Ground Neutral Failure

Rotor flux monitoring
Variances in the magnetic flux within a generator indicate deterioration of winding insulation. Imbalances within the rotor can damage insulation, degrading the generator’s output capacity and increasing vibrations. This further damages the insulation, leading to a forced outage. The system allows plants to detect variants early, and trend them over time:
- High – speed samples identify shorted turns
- Creates a generator health trend, and archives data:
- Identifies worsening shorts through real-time and historical measurements
- Provides early indication conditions leading to rotor ground faults
- Easy to install and does not require an outage
