A system includes a sensor configured to monitor rotating machinery and generate a signal based on a physical characteristic of the rotating machinery. The system also includes a monitoring system with a processor. The processor of the monitoring system is configured to receive the signal from the sensor. The processor determines an occurrence of reverse rotation of the rotating machinery by comparing the signal to a normal operating pattern to generate an initial value. The processor generates a notification signal indicating the occurrence of a reverse rotation.
