Product name: HCPQ301 portable power quality tester
Category: Electricity metering comprehensive test series

Detailed introduction

Product introduction

With the vigorous development of my country’s national economy, the power load has increased sharply, especially the continuous growth of impact and nonlinear load capacity, which has caused power quality problems such as waveform distortion, voltage fluctuation and three-phase imbalance in the power grid. The HCPQ301 power quality tester launched by our company is a high-performance multi-functional power quality test and analysis instrument. It adopts DSP+ARM+CPLD core and 5.5-inch large-screen LCD (320*240 dot matrix) display screen, making the structure more compact, more powerful and more convenient to display. The background management and analysis software is rich in functions and easy to operate.

Functional features

Easy to use: portable structure, small size, light weight, one person can carry the instrument to the site for testing; built-in high-performance lithium battery, continuous work for 8 hours without external power supply;

High precision: meets the requirements of national standard B-level instrument. Benchmark algorithms are used for harmonics and three-phase imbalance, without approximate calculations, and high-precision A/D (16 bits) is used for simultaneous sampling with an acquisition rate of 12.8kHz;

Powerful software functions: Using DSP+ARM+CPLD core, fast processing speed, rich software functions, suitable for complex testing and data processing, greatly improving testing efficiency and level;

Communication interface: The power quality tester provides a USB interface to facilitate data storage to a USB flash drive and communication with a laptop to transmit data;

Many test parameters: system frequency, grid harmonic one-phase voltage imbalance, voltage deviation, voltage fundamental RMS value and true RMS value, current fundamental RMS value and true RMS value, fundamental active power, active power, fundamental apparent power, 2-50th harmonics, true power factor and other parameters specified by the five major national standards for power quality;

Real-time harmonic data judgment: Real-time judgment of the voltage harmonics and current harmonics currently being tested Wave data is normal or exceeds the standard;

Background management and analysis software: Power quality management and analysis software is a set of power quality background management and analysis software, running on WIN9X/2000/XP/NT operating system, friendly, with graphics and curve analysis functions, and equipped with relevant information query, national standard query and other contents.
