SYSTEM AND METHOD FOR ESTIMATING MALFUNCTION OF ELECTRIC EQUIPMENT

摘要

PURPOSE: A failure prediction system and method for an electric installation are provided to implement accurate prediction by synthetically determining power information besides vibration information. CONSTITUTION: The power quality of an electric installation is calculated (S320). Triaxis vibrations of the electric installation are measured (S330). Different vibration information is calculated from the triaxis vibrations (S340). The power quality and the vibration information are transmitted (S350). The failure of the electric installation is predicted by the transmission.
