301 standard electric energy meter
301 standard electric energy meter
Product details
This product adopts advanced DSP technology, wide range technology, embedded computer technology design, as well as temperature self balancing technology. It is lightweight, small in size, leading in indicators, rich in functions, novel in interface, easy to use, and reliable in operation. Its functions and calculation methods comply with JJG 597-2005. The 301 series products can be widely used in the electric energy measurement and testing industry, electric energy meter and harmonic meter production enterprises, power laboratories and other related departments. They can be used in laboratories or carried to work on site, and all three phases can be used independently as single-phase standards. Product features ● Wide range measurement: Voltage signal measurement range (phase voltage) 1-680V, current signal measurement range 0.25mA-120A. Multi way measurement: It can measure AC voltage, current, power (active power, reactive power, apparent power) and electrical energy in four quadrants under various wiring modes such as single-phase and three-phase Y/Δ; Reactive power and electrical energy can be measured in multiple ways, including true reactive power, cross phase reactive power, and artificial neutral point reactive power. ● Multi functional measurement: In addition to measuring AC voltage, current, power, electrical energy (kWh), and harmonic analysis, it can also measure various parameters such as power demand, frequency, phase, power factor, power stability, amplitude and phase asymmetry of voltage and current, waveform distortion, electric energy pulse constant of the tested meter (as well as spatial magnetic induction intensity and voltage drop at the same end of the electric energy meter calibration device). Harmonic measurement: It can measure the content and amplitude of harmonics below the 50th order of power frequency voltage and current. Fundamental power measurement: It can be used for general full power measurement (including the power of the fundamental and various harmonics), or fundamental power measurement (only measuring the fundamental power component in signals containing harmonics). Harmonic power measurement: can measure 2-50th harmonic power. ● Electric energy error verification: It can verify the estimated values of electric energy measurement errors and standard deviations of electric energy meters and electric energy meter calibration devices. ● Multipurpose: It can be used as a standard meter or as a testing device for electric energy meters. It can be used independently, communicate with a PC for remote control, and can also be equipped with a calibration device for use. ● Voltage: 1~680V A.C. (phase voltage) ● Current: 0.00025~120A A.C. ● Frequency: 40~70Hz ● Harmonics: ≤ 30% ● Input pulse: max.120kHz (TTL) ● Output pulse: use automatic constant, at rated range, fout is 100kHz (TTL); When using artificial constants, the fout is 0.02Hz-1kHz (TTL) at the rated range. ● Power measurement accuracy: Active power measurement accuracy of 0.05% (PF ≥ 0.5) Reactive power measurement accuracy of 0.1% (PF ≥ 0.5) ● Electric energy measurement accuracy: Active energy measurement accuracy of 0.05% (PF ≥ 0.5) Reactive energy measurement accuracy of 0.1% (PF ≥ 0.5)
