Three-phase power quality meter, display and long-term memory

The three-phase measuring instrument permits the measurement and display of relevant power network parameters. It is able to measure single, two-phase or three-phase measurements. The display and operation is carried out by means of menu navigation with an LC display or the integrated Ethernet interface. The optional SCADA software provides for the display of all measurements and allows the implementation and analysis of intelligent networks (smart grids). The “smart meter” acts as a digital electricity meter where end customers are connected to the grid in order to measure electricity consumption and can be used to turn consumers on or off depending on the circumstances.
