Predictive maintenance (PdM) is a type of condition-based maintenance that tracks the condition of assets through sensor devices in real-time. That data is then used to predict when an asset will require maintenance and prevents equipment failure. With PdM, maintenance is scheduled only when specific conditions are met and before the asset breaks down.
Predictive maintenance techniques are designed to help determine the condition of electrical equipment in order to estimate when maintenance should be performed. Predictive maintenance is aimed at reducing risk and reducing costly, unexpected breakdowns. The idea is to instead manage maintenance around the production schedule.
