Prognostics and health management technologies are currently hot spots in the industry. This method can effectively improve the reliability of equipment and systems, reduce equipment downtime, and reduce equipment maintenance costs. This paper introduces the main methods of fault prediction and health management, analyzes and compares the advantages and disadvantages of different fault prediction techniques, combines the failure modes and failure characteristics of ceramic vacuum capacitors, and builds a Mahalanobis distance model to predict faults of ceramic vacuum capacitors. This method can effectively predict the time of failing, help companies develop maintenance plans in advance, and reduce e- quipment failure losses.
