Product Description

Product Description

GDPQ-300M Power
Quality Analyzer is used to monitor basic indexes like three-phase fundamental voltage, advanced, reactive power power factor and advanced indexes such as Inter-harmonics, voltage fluctuation, flicker, voltage swell & sag, temporary over-voltage and transient over-voltage.
Industrial PC is used for data calculation, statistics, display, storage, keystroke and communication. XPE embedded operating
system is adopted as the software platform, and all the software is programmed with VC++ high-level language, which guarantees the high reliability and high transplantation of the system.
The FPGA data acquisition adopts 16-bit high-speed A/D converter with 6 channels and synchronous sampling, which has high acquisition accuracy, and the measured accuracy meets the requirements of national class A standard of power quality monitoring
index.
The hardware phase locked loop technology is adopted to automatically track the frequency, which prevents the influence on the monitoring index when the frequency of the power system changes, and prevents the frequency "leakage". The core hardware adopts four-layer printed circuit board (PCB) process and SMT process, and the hardware reliability and EMC capability reach the advanced level in China, and meet the EMC requirements of international standard for power quality monitoring device.
