Brief Introduction
ST1000 high precision three-phase reference standard energy meter is developed our company. It adopts high accuracy A/D and DSP. It can be used for measurement of AC voltage, current, active power, reactive power, apparent power, power factor, phase, frequency and so on, and it can harmonic analysis, computer energy meter error.
Features and Functions
1. Wide range measurement: Voltage measurement range( phase to phase) 1V~480V, current measurement range 1mA~120A; Once wiring without switch
2. Multimode measurement: AC voltage, current, active power, reactive power, apparent power and energy measurement in single/three phase Y/Δ various circuits in four quadrants. Reactive power and energy can measure true reactive power and cross phase reactive etc.
3. Multifunctional measurement: Besides the measurement of AC voltage, current, power and energy, measurement of frequency, phase, power factor, power stability, energy demand, dissymmetry of three phase system and waveform distortion etc. also can be done
4. Harmonic power measurement: analysis the active/reactive power of 2nd~50th harmonic
5. Energy error testing: Energy metrology error and estimated value of standard deviation of energy meter and energy meter test equipment can be tested
6. Data and diagram display: measurement state and various measurement data, actual voltage and current wave form, voltage and current phase vector diagram and harmonics spectrum display
7. Record and query: Real measurement condition record, query and redisplay at any time
8. Wiring: current input from 1Ma to 120A share a group of terminals. change current, no need to change the wiring
