The HZCR-5000 Power Quality Analyzer is a comprehensive test instrument designed for field testing of three-phase systems. It is multifunctional, intelligent, and user-friendly, featuring a large high-resolution LCD screen, dual-language interface (Chinese and English), and a shockproof shell. It measures 4-channel current (ABC three-phase and neutral), 4-channel voltage (ABC three-phase and neutral-to-ground), peak current and voltage values, maximum/minimum values over a period, three-phase imbalance factor, short-term voltage flicker, transformer K factor, active, reactive, and apparent power, power factor, displacement power factor, total harmonic distortion, and harmonics. It displays real-time waveforms and harmonic ratio bar charts, dynamically captures instantaneous changes in voltage and current, monitors inrush current, and generates alarm lists and trend charts for long-term data recording. Introduction: The HZCR-5000 adopts a DSP + ARM dual-processor architecture. The DSP handles data acquisition and algorithm processing, while the ARM manages communication protocols and the user interface. Analog signal acquisition is performed by two AD7655 chips (16-bit, 4-channel synchronous sampling, up to 1 MSPS), ensuring accuracy and integrity. The 5.6-inch color LCD screen (640 x 480) provides clear visualization of phase, waveform, vector diagram, and harmonic ratio. Built-in flash memory stores 60 screenshots, 150 transient waveforms, and 12,800 alarm logs. The inrush current detection mode captures waveforms for 100 seconds. A 2G memory card records trend curves, storing data for up to 300 days. Functions: - Real-time waveform display (4 voltage/4 current channels) - True RMS values of voltages and currents - DC components of voltages - Peak current and voltage values - Minimum and maximum half-cycle RMS values - Phasor diagram display - Measurement of each harmonic up to the 50th order - Bar charts show harmonic ratios - Total harmonic distortion (THD) - Active, reactive, apparent power (per phase and cumulative) - Active, reactive, apparent energy (per phase and cumulative) - Transformer K factor - Power factors (PF) and displacement factors (DPF or COSΦ) - Short-term voltage flicker (PST) - Three-phase imbalance (current and voltage) Advanced Functions: - Transient capture function: Monitors instantaneous changes in power grid voltage/current, including fluctuations, surges, sags, interruptions, overvoltage, impact current, and instantaneous distortion. Stores 150 sets of transient waveforms. - Starting current monitoring: Monitors surge and startup current, displays RMS rising/falling curve, envelope curve, and waveform of 4 channels current/voltage. Records about 100s after trigger. - Trend chart recording and storing: Stores all test parameters, 50 voltage harmonics, 50 current harmonics, creates trend curves. Records up to 300 days (20 parameters every 5 seconds). - Alarm function: Set limit values, monitor for overshoot, generate alarm logs (voltage, current, unbalance, harmonic ratio, frequency, active power, THD). Configure 40 different alarms, up to 12,800 logs. - Snapshot function: Any screen can be saved (up to 60), automatically records time and test mode. - Communication function: USB connection to computer, monitoring software displays waveform, reads transient waveform, trend chart, alarm log, screenshots. - Setting function: Configure time/date, screen contrast/brightness, phase curve colors, connection type, sensor/voltage ratios, menu language (Chinese/English). - Help menu: Chinese/English help at every operation stage.
