    GF3121 wireless three-phase kWh meter site verification

    Application

    It is suitable for measuring power grid companies test center, power supply company , power supply management, power metering, technical supervision department, industrial and mining enterprises, petroleum, chemical industry, electric power measure of the department.

    Main Functions and Features

    1, Test single-phase and three-phase induction type, mechanical and electrical meter; and it can also test two different constants of watt-hour meter;

    2, Real-time field measurement three-phase voltage, current, active power, reactive power, phase, power factor, frequency, power, and a screen display all measured parameters;

    3, Measure CT variable ratio; Display voltage current vector diagram and check the wiring errors, giving the wrong wiring state power loss;

    4, Several way of power supply, external AC power supply, it also can line voltage power supply;

    5, Dynamic tracking load changes, the voltage, current fluctuating site also can steadily calibration watt-hour meter error;

    6, Divided into direct measurement and current clamp measurement, good stability, safety and reliability;

    7, Optional 5 A, 20 A, 100 A, 500 A, 1000 A, 2000 A current clamp;

    8, Measure 2 ~ 63 times harmonic content, showed great harmonic wave diagram and the figure, the harmonic analysis;

    9, With micro printer, but the spot printing; And take barcode scanners to be automatic scanning electric energy meter, the table;

    10, With intelligent photoelectric sampler, convenient to the pulse to adopt several watt-hour meter.

    11, Big screen color liquid crystal display, simple operation, convenient; the large capacity memory, it can store 5000 sets of data;

    12, With RS232 interface, which can be the scene of the measurement data storage will be turning to the computer analyzed with;

    13, With wireless PDA, convenient operation and data management.
