Product Description

3-Phase Power Quality Analyzer Uni-t Voltage and Current Diagnostic Tool
for Power Quality Analysis
 

Introducing the Power Quality Analyzer

The Power Quality Analyzer is a high-precision testing instrument specially used to detect power quality issues in power grids such as waveform distortions, harmonic content, three-phase imbalances, etc. It also has the functions of electrical parameter testing and vector analysis. It can accurately measure various electrical parameters including voltage, current, active power, reactive power, phase angle, power factor, frequency and so on. It can display vector diagrams of the measured voltage and current. By analyzing the vector diagrams, the user can determine whether the metering device is correctly wired.

Describing the Power Quality Analyzer

1. The current is measured by means of a clamp transformer: it can be measured conveniently and safely without disconnecting the current circuit. Clamp meter with different ranges is optional.
2. It can measure and analyze the quality of AC power supplied from the public grid to the user's end: frequency deviation, voltage deviation, permissible unbalance of three-phase voltage and grid harmonics.
3. Simultaneously display single-phase voltage and current waveforms and three-phase voltage and current waveforms. 7.
4. Load fluctuation monitoring: measure and analyze the fluctuation of power quality of public power grid caused by all kinds of power-using equipments in different operation states. Record and store the trend of voltage, current, active power, reactive power, apparent power, frequency, phase and other power parameters at regular intervals.
5. Adjustment of power equipment and dynamic monitoring of the operation process: it can test and analyze the dynamic parameters of reactive power compensation and filtering devices in the power system and make quantitative evaluation of their functions and technical indexes.
6. Built-in large-capacity data memory, adjustable storage interval from 5 seconds to 5 minutes: more than 18 months of continuous storage at 1-minute intervals can meet the needs of long-term monitoring test points.
7. built-in high-capacity, high-performance carp ion rechargeable batteries, fully charged for more than 10 hours of continuous work. 3 minutes of no operation LCD automatically enters the power-saving mode, in order to maximize the battery operating time.
8. Small size, light weight, easy to carry. Can be used for on-site measurement, can also be used as a laboratory standard measurement equipment.
