Brief Introduction
ST1001 Reference Harmonic Power Meter is the development of the latest class0.01 harmonic standard, which NIM authorized Star to use “non-period sampling compensation algorithm” technology to develop it. Measurement channels are using high stable components, measurement index
Of foundational active power and harmonic active power reach high accuracy (class0.01). The harmonic standard can be used for testing normal foundational energy meter, GB/T17215 5th harmonic effect, harmonic energy meter, and energy quality analysis instrument and power harmonic monitor instrument.
Features and Functions
- High accuracy measurement: accuracy of fundamental active power and harmonic active power measurement can reach to class0.01, accuracy of harmonic amplitude and harmonic reactive power measurement can reach to class 0.02
- Comprehensive measurement Harmonic parameter: measure 6 lines signals of harmonic parameter at the same time, comprehensive measure amplitude, Phase Angle, harmonic active power and harmonic reactive power of 2nd~50th harmonic signal.
- Wide range signal measurement: Voltage signal measurement range( phase to phase) 1V～480V, current signal measurement range 1mA～120A
- Multifunctional testing: testing normal foundational energy meter, harmonic energy meter, energy quality analysis instrument, electronic harmonic monitor and other meters.
- data and diagram display: TFT color LCD, display every harmonic voltage, current amplitude, phase, harmonic power and total harmonic power: display measurement status of working and many measurement data; Display measured voltage, current wave, voltage and current phase, vector diagram, harmonic analysis Histograms
- Wiring easily: all input current share a group terminal. When change current, no need to change the wiring
- data record and easy query: record and search measured result
