Predictive maintenance

Definition

Predictive maintenance is a proactive approach to maintenance that utilizes data analysis and monitoring techniques to predict when equipment failures might occur, allowing for maintenance to be performed just in time to prevent unplanned downtime. By analyzing data from sensors and historical performance, this method helps optimize equipment performance and extends its lifespan. It is particularly significant in environments where reliability and efficiency are critical, such as in smart grid systems.
