Abstract: An approach for detecting rotor anomalies is disclosed. Vibration data for a vibration sensor(s) and for a transient speed operation is classified into a plurality of rotor speed ranges. A predetermined percentile vibration amplitude is determined for each rotor speed range for the vibration sensor(s). Using historical vibration measurement data obtained from a predetermined number of previous transient speed operations performed by at least the rotor, it is determine whether a vibration measurement obtained during the transient speed operation is indicative of a rotor anomaly by determining whether a trend exists in the predetermined percentile vibration amplitude for at least one of the rotor speed ranges and the vibration sensor(s) over a preset number of previous transient speed operations. A rotor anomaly is indicated where a trend exists.

Abstract: An Arc Fault Circuit Interrupter support system and program, having a plurality of sequenced individual loads arranged in scenes or groups, which sequenced individual loads when activated together form a cumulative total of 800 watts or more; and one or both of a delay between each sequenced individual load to prevent the cumulative wattage from creating a nuisance Arc Fault Circuit Interrupter breaker trip, and a plurality of pre-heat pulses provided to individual loads with individual wattages of 800 watts or more prior to applying a full current to the individual load.
