Huazheng HZZ4000 Power Quality Analyzer is a comprehensive test instrument developed by our company, specifically designed for field testing of three-phase systems. It is a multi-functional, intelligent device with an intuitive man-machine interface. The analyzer is user-friendly, featuring a large LCD screen with high resolution, and it supports both Chinese and English interfaces. Its shock-proof shell ensures durability in various environments. The HZZ4000 can simultaneously measure four channels of current (three-phase ABC and neutral wire current) and four channels of voltage (three-phase ABC voltage and neutral-to-ground voltage). It provides detailed measurements, including the peak values of current and voltage, maximum/minimum values over a period, three-phase imbalance factor, short-term voltage flicker, transformer K factor, active power, reactive power, apparent power, power factor, displacement power factor, total harmonic distortion, and harmonic levels. The analyzer displays real-time waveforms and harmonic ratio bar charts for current and voltage. It can dynamically capture instantaneous changes in voltage and current, monitor starting currents, and track power parameters. The device also generates alarm notifications, creates long-term trend charts, and stores test data for future analysis.

Products Description

I. Introduction

In modern power applications, large power equipment and increasingly complex power grid faults are becoming more prevalent. As industrial development continues, the demand for higher quality electric energy is rising. To address these challenges, we provide the HZZ4000 Power Quality Analyzer, which allows for faster and more accurate troubleshooting of complex power systems, as well as more comprehensive and systematic monitoring and maintenance of power quality parameters."

"The HZZ4000 Power Quality Analyzer utilizes a dual-processor architecture with DSP and ARM processors. The DSP is responsible for data collection and algorithm processing, while the ARM handles communication protocols and man-machine interface tasks. Analog signal acquisition is achieved through two ADC chips from ADI, with a 16-bit resolution and 4-channel synchronous sampling. The highest sampling rate reaches 1 MSPS, ensuring accurate channel measurements and data integrity, without missing any transient changes in the grid. This enables precise detection of rapid waveform rises, drops, and instantaneous interruptions."

"With a DSP working frequency of over 200 MHz, the analyzer can monitor the power grid in real time and dynamically adjust the sampling frequency to ensure synchronization with the power frequency. The device features a 5.6-inch LCD color display with a resolution of 640 x 480 pixels, offering clear visual distinctions between phase parameters, waveforms, vector diagrams, and harmonic ratios. This helps users more efficiently and intuitively understand the state of the power grid."

"The analyzer's built-in flash memory can store up to 60 screenshots, 150 transient voltage/current waveforms, and 12,800 alarm entries. It also features a starting current detection mode, which continuously captures starting current waveforms for up to 100 seconds. A built-in 2GB memory card stores trend curve records, capturing data for 20 parameters (selectable based on needs) every five seconds. These trend curve records can be kept for up to 300 days."

"The Power Quality Analyzer, also known as the Intelligent Three-Phase Power Quality Analyzer or Multifunctional Power Quality Analyzer, integrates the functions of a harmonic analyzer, phase volt-ampere meter, and electrical parameter tester. It is suitable for use in industries such as electricity, petrochemicals, metallurgy, railways, mining, scientific research institutions, and metrology departments. It is especially valuable for comprehensive analysis and diagnostics of voltage, current, power, harmonic, and phase electrical parameters.
