General Overview In three-phase systems, the device measures the RMS values of AC network voltages and currents for each phase, displaying the total active energy (ΣkWh) on its screen. Users can configure the current transformer primary value and the voltage transformer ratio. This device provides all the parameters required by automation companies working on energy saving, network analysis, and production cost analysis, while also offering cost savings through its price.

Integration and Data Access The device can be easily integrated into SCADA systems using the MODBUS-RTU protocol via the RS-485 port. Through the register table, it is possible to access:

• Phase-to-neutral voltages, phase-to-phase voltages, currents, neutral current, frequency, and power factors (PF) for each phase.

• Power factor distortion (PFD), import/export active powers, and reactive powers.

• Active and reactive energy values.

• Amplitude and percentage values of all odd harmonics from the 3rd to the 31st for both currents and voltages.

• Zero-crossing angles for currents and voltages of all three phases.
