The system deploys infrared sensors around the carbon brushes and slip rings, combined with ultrasonic and surface wave acquisition, to form a continuous imaging coverage over the entire brush and slip ring assembly. This enables comprehensive, uninterruptedmonitoring of the generator excitation carbon brushes and slip rings with no blind spots or gaps.

Through the backend monitoring system, the overall temperature field is tracked in real time, with over-temperature alarm functionality. It provides earlywarnings for initial sparking anomalies, monitors degradation trends, and delivers real-time alerts along with handling strategies to prevent serious failures in the excitation carbon brush system.
