              Products Features:

1. The power quality analyzer is a high-precision testing instrument specially used to detect power quality 

    problems such as waveform distortion, harmonic content, voltage fluctuation and flicker and three-phase 

    imbalance in the power grid; it also has electrical parameter testing and vector analysis Function of

2. It can accurately measure various electrical parameters such as voltage, current, active power, reactive

    power, phase angle, power factor, frequency, etc.

3. The vector diagram of the measured voltage and current can be displayed, and the user can obtain the 

   correctness of the measurement equipment wiring by analyzing the vector diagram

4. The current is measured using a clamp transformer. Because the operator does not need to disconnect

    the current loop when measuring with a clamp current transformer, the measurement can be performed
         conveniently and safely. According to the user's different measuring range, you can choose
         different range of clamp meter

5. It can measure and analyze the AC power quality supplied by the public power grid to the user. Its measurement 

   and analysis: frequency deviation, voltage deviation, voltage fluctuation, flicker, three-phase voltage
         allowable unbalance and grid harmonics

6. Single-phase voltage and current waveforms can be displayed and three-phase voltage and current

   waveforms can be displayed simultaneously

7. All test interfaces have screen lock function to facilitate user reading and analysis data

8. Load fluctuation monitoring: measure and analyze the fluctuations caused by various electrical equipment

    to the power quality of the public power grid under different operating conditions. Regularly record and store 

   changes in power parameters such as voltage, current, active power, reactive power, apparent power,
         frequency, and phase

9. Dynamic monitoring of power equipment adjustment and operation process to help users solve problems 

   arising during power equipment adjustment and commissioning

10. Ability to test and analyze the dynamic parameters of reactive power compensation and filtering devices in the 

   power system and make quantitative evaluations of their functions and technical indicators
