Predictive maintenance based on condition monitoring

The data necessary for predictive maintenance in electrical power distribution is already available in most buildings. This data is acquired and processed by measuring devices and sensors that collect energy and condition data and by software that visualizes and evaluates relevant values.

The technical implementation is relatively easy, thanks to the use of power monitoring systems. Energy and condition data is usually measured by special measuring devices or communication-capable protection and switching devices. These devices precisely,

reliably, and reproducibly measure electrical values like voltage, current, and output for infeeds and outgoing feeders and individual systems and consumers all the way down to the plant level.

They also supply information for assessing power quality and system states – data that is essential for predictive maintenance.
