Generator Field Monitoring system

Generator Field Monitoring system

Cutsforth™ Premium Shaft Ground Monitoring and Rotor Flux Monitoring systems combine to make one powerful Generator Field Monitoring program.

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
