Rotor Flux Monitoring System

The Rotor Flux Monitoring system tracks the magnetic flux within a generator. Variances in magnetic flux indicate deterioration of winding insulation. Whether a result of thermal wear, large variation on load, contamination, or other causes, the impact to efficient generation is significant. Imbalances within the rotor damages insulation, which in turn degrades the generator’s output capacity and increases vibrations, further damaging the insulation, which ultimately leads to a forced outage. Once the monitoring system collects the rotor flux data from the probe, the data is then ported directly into Cutsforth's InsightCM online asset monitoring software for viewing and alarm setting in the control room or any authorized remote location.
