Predictive Maintenance in Generator Protection

Predictive maintenance aims to anticipate equipment degradation and potential failures before they occur. This allows for preventative actions to be taken, minimizing downtime, maintenance costs, and the risk of catastrophic equipment failures.  Here's how it integrates with generator protection:

Advanced Sensor Integration:  Modern protection systems incorporate various sensors beyond traditional voltage and current measurements.  These sensors can monitor vibration, temperature, speed, and other critical generator parameters.  Continuous monitoring of these parameters provides valuable data for fault prediction.

Data Acquisition and Analysis:  Advanced data acquisition systems collect data from various sensors at high sampling rates.  This data is then fed into powerful data analytics tools for processing and interpretation.

Machine Learning Algorithms:  Machine learning algorithms are trained on...
