(1) Real-time measurement function

          - Three-phase voltage, three-phase current；

          - Three-phase active power, three-phase reactive power, three-phase power factor；

          - Total active power, total reactive power, total power factor；

          - Three-phase voltage 3~25th harmonic, three-phase current 3~25th harmonic；

          - Real-time waveforms of three-phase voltage and current；

          - Three-phase voltage and current harmonics 3-25th histogram；

(2) Intelligent networking

         It can be automatically networked through the bus mode, and can accommodate 48 integrated fast harmonic suppression reactive power compensation devices without manual intervention.

(3) Parameter setting

         Some parameter values can be set by pressing the keys.

（4）Automatic/manual control

         You can freely switch the system to automatic switching mode or manual control mode. In automatic mode, the program automatically performs switching operations, and manual mode requires manual control of the reactive power compensation device for switching.

(5) Protection function

         Overvoltage, undervoltage, phase loss, over-harmonic blocking, switch failure.

(6) Human-computer interaction

        Real-time display of various electrical measurement data, parameter information and operating conditions on the display panel.
