    Single Phase Energy Meter Calibration Equipment For Electric Power System

    Single Phase Energy Meter Calibration Equipment For Electric Power System


    1. Overview


    The XL-821A single-phase programmable standard power source is a new generation of high-precision standard power source based on 1.2 G MAC DSP, large-scale FPGA, high-speed and high-precision DA and high-fidelity power amplifier. Applicable to electric power system, electric power, remote control, dispatching and other power departments and enterprises that need measurement, inspection and high-precision standard signal sources. It is also suitable for other occasions where high-precision standard signal sources are required for measurement and inspection.
    XL-821A can output high-precision voltage and current with adjustable frequency, phase and amplitude at power frequency (40Hz~65Hz). It is a highly accurate adjustable voltage and current standard source. The XL801 can output very pure sinusoidal voltage current with a distortion of no more than 0.1%, typically 0.03%. The XL-821A's voltage-to-current output has very high output stability, typically 0.004% RD. Therefore, it is very suitable for work situations requiring high-precision inspection and calibration, such as the measurement department for the detection of various voltage, current, power and other electrical parameter meters.


    2. Main features


    1) It is possible to output a pure sinusoidal power signal with a distortion of 0.03% (typical).
    2) Each harmonic output can be superimposed on the fundamental wave.
    3) The frequency output can be adjusted from 40Hz to 65Hz, the resolution is 0.002Hz, and the accuracy is 0.002Hz.
    4) The phase 0~360 degrees can be adjusted arbitrarily, which can easily simulate various power supply situations and even reverse power transmission.
    5) Strong load capacity, can carry capacitive, inductive, resistive load or composite type load, and the load regulation rate is better than 0.01% RG.
    6) Excellent temperature stability, the core device is a military grade product with a temperature coefficient as small as 1PPM, which can guarantee the output precision in the outdoor temperature environment.
    7) It is powerful and flexible with 32-bit MCU+DSP processor.
    8) The waveform of the power frequency is up to 50,000 points per week. The internal signal output is smoothed without filters, which ensures the accurate output of the waveform, so that the system can output accurate harmonics and the system has excellent harmonic distortion. index.
    9) It can be easily connected to the PC through an RS232 to expand other functions.
    10) Perfect overcurrent, overvoltage, overheat, short circuit, open circuit, overload protection.
    11) Hardware PID, the response is extremely fast, and the change of load will not cause the fluctuation of the output.
    12) 320*240 liquid crystal display, Chinese interface, easy to operate.
    13) Open communication protocol to facilitate secondary development (factory automatic verification of RTU/FTU/power management terminal/common measurement terminal).
    14) It can be loaded with pure capacitive load, and the power meter can be checked with PC software.

    3. Main functions


    Main function Description
    AC standard source output can output power frequency (40Hz ~ 65Hz) frequency, phase and amplitude adjustable high-precision voltage and current, convenient for power workers to develop, verify
    Transmitter verification for voltage, current, power verification
    Communication function Used to communicate with PC and other main control modules, only supports "Programmable Power Interface Protocol"
    Power check function for verifying energy pulse input
    User-defined functions User-definable function output, but requires functions that do not contain DC components
    Secondary development Users can refer to the "Programming Power Interface Protocol" to develop various functions required through the communication port.
    Software control function Equipped with XL-3900 series operating software, as long as the device power is turned on and the communication line is connected, it can be controlled freely on the PC, which is convenient and quick.
    Local function with 320*240 LCD display, 24 buttons and rotary encoder for local operation
    Alarm function When the device is abnormal, the system will automatically start the protection program, accompanied by a sound or interface pop-up prompt. At this time, the user should power off and find the cause of the fault and eliminate it, such as voltage to ground short circuit, current open circuit output.
