Production plant operating method, involves continuously detecting electrical current and/or voltage, analyzing and comparing detected electrical current and voltage, and supplying electrical current and voltage

摘要

The method involves continuously detecting electrical current and/or voltage using a measuring device (6) that is provided at a plant-lateral network (3) which is attached to an external electricity supply network (1). The detected electric current and the voltage are analyzed with a computer aid and compared with values determined during computer simulation. The electrical current and the voltage are supplied by an autonomous communication line of a distant monitoring station (9), where the autonomous communication line is separated by an Intranet of a production plant (2). An independent claim is also included for a measuring device comprising a device-sided memory.
