major function

metering function

Measure reactive power in both forward and reverse directions; Input/output fundamental and harmonic active energy measurement; Harmonic analysis (can calculate the harmonic voltage and current content, content, and total distortion rate).

parameter monitoring

It can monitor real-time values of voltage and current in each phase, as well as real-time parameters such as active power, reactive power, power factor, phase angle, and phase of the three-phase total and phases A and C.

Time-sharing measurement

Time division metering of forward and reverse active power, four quadrant reactive power, and maximum demand.

display function

Wide viewing angle, large screen LCD display, with rich status indication and Chinese character auxiliary prompt information; It can display the monthly electricity consumption data for the past three months.

Storage

Can store 12 months of historical electricity data.

Load curve function

Capable of recording load curves for 6 types of data; You can freely choose to draw a curve graph from data such as voltage, current, frequency, power and power direction, power factor, total reactive power, four quadrant reactive power, current demand, etc.

Anti electricity theft function

It has the function of recording events such as lid opening, voltage loss, current loss, phase failure, current imbalance, power failure, reset, reverse phase sequence, and reverse power being included in forward power, to prevent users from illegally removing or cutting off voltage and current connections.

communication

Meter reading can be achieved through button display, infrared handheld device, and RS485 communication interface. Combined with the meter reading system, it can read various electricity data of the meter and support DL/T645-2007 communication protocol.

Suitable for power plants, substations, and various enterprises and institutions that require high reliability and high stability electricity metering.
