Industry 4.0 enables us to predict the future condition of the installation, based on historical data powered via PoE. Doepke e.Guard is a flexible system combining both hardware and software components in order to continuously monitor electrical installations. This allows you to keep a close eye on an installation's status and so to dispense with repeated insulation testing according to DIN VDE 0105-100/A1, for example. What's more, with the aid of machine learning (ML) methods, the residual current data collected by the system can be used to deduce trends that indicate how the installation might behave in the future. As a result, e.Guard enables you to take planned action at an even earlier stage, thereby increasing safety and minimising risks for your company. The system offers custom installation monitoring – from a flexible stand-alone solution for smaller set-ups through to fully integrated monitoring within system landscapes made up of complex industrial structures.
