Patent number: 11959825Abstract: A method for monitoring a rotating equipment through a condition monitoring device is performed in every predetermined time period after every predetermined time interval. The method comprises detecting presence of vibration in rotating equipment based on a signal associated with vibration in the rotating equipment. The signal is measured with one or more sensors of the plurality of sensors. Upon detecting presence of vibration, a predefined number of samples associated with the vibration is acquired at a first frequency. A Root Mean Square (RMS) value of vibration is calculated using predefined number of samples. The calculated RMS value of vibration is compared with a reference value for detecting an operating status, which is stored for every predetermined time interval. Thereafter, the method comprises processing the stored information to assess a condition of the rotating equipment.Type: GrantFiled: May 26, 2020Date of Patent: April 16, 2024Assignee: ABB Schweiz AGInventors: Maciej Orman, Manuel Oriol, Pallavi Hujband, Prasad Venikar, Tejas Atul Trivedi, Neethu T.
