Power and energy meterFunctions· measurement· data recording· events recording· disconnecting certain consumersMeasurement functions· 3 phase/line voltages and their average· 3 phase currents and their average· Active, reactive, apparent, three-phased and per each phase power· Active, reactive, apparent energy: import, export· Three-phased and single-phased power factor· Average active, reactive power during integration period· Frequency· Minimum and maximum for each measured parameter· Average values for each measured parameter· Voltage or current irregularities· 31 current and voltage harmonics· Wave shapesMeasurements local display on the deviceIf the device is supplied with integrated display, the required parameters can be locally displayed (on the device), for example:· Average power in progress· Power limits for warning· Power limits for disconnection· Voltages, currents· Measured energy The display has 8 (user) programmable displays, each having the required parameters. Each display has he possibility of displaying one, two, three or four simultaneous parameters. In case the device is equipped with display, all panel measurement devices from the cell where the ION is mounted can be discarded (ampermeters, voltmeters, meters, power indicators, cosφ meters etc.)
