Abstract: The present disclosure provides a method for detecting an electrical discharge in an electrical apparatus. The method includes sensing an electromagnetic wave using an electrical sensor and generating an electric signal for a predetermined time period, sensing an acoustic wave using an acoustic sensor and generating an acoustic signal for the predetermined time period. The acoustic sensor is associated with at least one compartment of the electrical apparatus. Electrical data is generated based on a quasi-periodic characteristic of electric peak sequences of the electrical signal. Acoustic data is generated based on a quasi-periodic characteristic of acoustic peak sequences of the acoustic signal, wherein the electrical data is combined with the acoustic data to provide an operation status of the at least one compartment.

Abstract: In one aspect, a system includes at least one processor configured to identify a digital image of the process station generated during an operation of the process station, identify, in the digital image, a visual indicator of the process station, and analyze the visual indicator to identify a current state of the visual indicator. The at least one processor is further configured to identify configuration data for the process station that defines an expected state of the visual indicator, determine whether the current state deviates from the expected state, and generate indicia representing the identified current state in response to determining that the current state deviates from the expected state.
