WXE8000 Online Power Quality Monitoring Device

Product Introduction

WXE8000 Online Power Quality Monitoring Device is primarily used for measuring and analyzing the AC power quality supplied from the public grid to the user end.Its measurement and analysis cover:frequency deviation,voltage deviation,voltage fluctuation and flicker,and the permissible three-phase voltage unbalance degree.It measures and analyzes the impact of various electrical equipment on public grid power quality under different operating conditions.

Instrument Features

1. Safe and Reliable:Voltage input utilizes high-voltage isolation modules,and current input utilizes high-precision current transformers,ensuring safe isolation between the input signals and the measurement system.This significantly enhances the anti-interference capability of the WXE8000.
2. Easy to Use:Features a Chinese interface and simple button operations,making it more convenient for users.
3. High Accuracy:Complies with Class A instrument requirements per national standards.For harmonics and three-phase unbalance,benchmark algorithms are used without approximation.It employs high-precision 16-bit A/D with a simultaneous sampling rate of 12.8 kHz.
4. Powerful Software:Utilizes a DSP+ARM+CPLD core,offering fast processing speed and rich software functionality.This makes the WXE8000 suitable for complex testing and data processing tasks,greatly improving testing efficiency and capability.
5. Communication Interfaces(RS-232/485,Ethernet Port):The WXE8000 typically uses RS-232 to RS-485 communication.Ethernet communication requires separate specification in the contract.Pin 2:RS-232 Transmit(TXD),Pin 3:RS-232 Receive(RXD),Pin 5:RS-232 Ground(GND).
6. Multiple Test Parameters:System frequency,three-phase voltage unbalance,voltage deviation,frequency deviation,fundamental and true RMS values for voltage and current,apparent power,active power,reactive power,harmonics up to the 63rd order,inter-harmonics up to the 50th order,power factor,transient waveform recording,flicker,and other parameters specified in national power quality standards.
7. Large Capacity Storage:The online power quality monitoring device has built-in 512MB memory.It stores data in 5-minute intervals and can continuously store historical data for one year.

Main Applications
