HZDZ-S Portable Three Phase Power Quality Analyzer with Harmonic Analysis, Voltage & Current Measurement, and Energy Monitoring Tester.

Power quality refers to the AC power quality at the user's end as supplied by the utility grid. When power quality is interfered with and polluted, it becomes necessary to identify the causing reasons and improve the power quality to eliminate unsafe hidden dangers.

1. The instrument is a high-precision test instrument specially used for detecting power quality problems such as waveform distortion, harmonic content, and three-phase unbalance occurring in the power grid. It also has the functions of electric parameter testing and vector analysis.
2. Accurately measures voltage, current, active power, reactive power, phase angle, power factor, frequency, and other electrical parameters.
3. Displays the measured voltage and current vector diagram. Users can analyze the vector diagram to determine the correctness of the wiring of the measuring equipment.
4. Current is measured by means of a clamp-on transformer. Because the operator does not need to disconnect the current circuit when measuring with the clamp-on current transformer, measurement is convenient and safe. Different ranges of clamp meters can be equipped according to the user's measurement range.
5. Measures and analyzes the quality of AC power supplied from the public grid to the user end, including frequency deviation, voltage deviation, three-phase voltage unbalance, and grid harmonics.
6. Displays single-phase voltage and current waveforms, and can simultaneously display three-phase voltage and current waveforms.
7. All test interfaces feature a screen lock function to facilitate user reading and data analysis.
8. Measures short-time flicker Pst and long-time flicker Plt.
9. Load fluctuation monitoring: measures and analyzes the fluctuation of power quality of the public power grid caused by various power equipment in different operating states. Regularly records and stores the trend of voltage, current, active power, reactive power, apparent power, frequency, phase, and other power parameters.
10. Records the active power and reactive power consumed at the test point.
