1.Overview

With the vigorous development of the national economy, the power load has increased sharply, especially the continuous growth of impact and non-linear load capacity, causing power quality problems such as waveform distortion, voltage fluctuation and flicker, and three-phase imbalance in the power grid. The portable power quality analyzer introduced by Goldhome hipot is a high-performance multi-function power quality analyzer. Using DSP+ARM+CPLD core, 3.2" large LCD (320×240 dot matrix) display, making the structure more compact, more powerful, and more convenient to display. The background management and analysis software of Portable Power Quality Analyzer is rich in functions and easy to operate.

3. Main functions and features

3.1 Safe and reliable

The voltage input uses a high voltage isolation module (2000V, response time ≤ 2μS), and the current input uses an alternating current clamp (0～50KHz, 0～5Arms) to safely isolate the input signal from the measurement system. This not only makes the power quality analyzer safe, reliable and convenient to use, but also greatly improves the anti-interference ability.

3.2 Easy to use

Portable Power Quality Analyzer has portable structure, small size, light weight, one person can carry the instrument to the site for testing; built-in high-performance lithium battery, no external power supply.

3.3 High accuracy

For harmonics, three-phase unbalance, flicker, and fluctuations, reference algorithms are used, without approximate calculations, high-precision A/D (16-bit), simultaneous sampling, and a sampling rate of 12.8 kHz.

3.4 Strong software function

Using DSP+ARM+CPLD core, fast processing speed and rich software functions, the power quality analyzer is suitable for complex test work and data processing work, and the test efficiency and level are greatly improved.

3.5 Communication interface

The harmonic tester provides a USB interface, which is convenient for communication and data transmission with a laptop computer.

3.6 Many test parameters

System frequency, grid harmonics, three-phase voltage unbalance, voltage fluctuation and flicker, voltage deviation, voltage fundamental RMS and true RMS, current fundamental RMS and true RMS, fundamental active power, active power , Fundamental apparent power, 2-52 harmonics, true power factor and other parameters specified by the five major national standards for power quality.

3.7 Mass storage

The harmonic tester has a built-in 32MB memory, and users can configure different storage time steps, including 5 seconds, 15 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes, 15 minutes, 30 minutes, etc.

4.The main purpose

4.1 Measurement and analysis of the AC power quality supplied. Measurement and analysis: frequency deviation, voltage deviation, voltage fluctuation and flicker, three-phase voltage allowable unbalance, and grid harmonics.

4.2 Apply wavelet transform to measure and analyze the harmonics of non-stationary time-varying signals.

4.3 Measurement and analysis of various electrical equipment on the power quality of the public grid under different operating conditions.

4.3 Load fluctuation monitoring: regularly record and store the change trend of power parameters such as voltage, current, active power, reactive power, apparent power, frequency, and phase.

4.4 Dynamic monitoring of power equipment adjustment and operation process, to help users solve problems in the process of power equipment adjustment and commissioning.

4.5 Test and analyze the causes of failures such as circuit breaker operation, transformer overheating, motor burnout, and automatic device malfunction in the power system.

4.6 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.

4.7 The characteristics of portability, multi-parameters, large capacity, high precision, and the application of modern signal analysis theories make the power quality analyzer widely used in fields such as power transmission and distribution, power electronics, and motor driving.
