Overview

The PQMA power quality monitoring device is designed according to the national standards for power quality and relevant IEC standards. It adopts new technological achievements such as high-speed DSP chips, high-resolution AD converters, and large capacity electronic disks. Accurate measurement and calculation of power quality indicators such as harmonics, voltage, frequency, flicker, and three-phase voltage imbalance have been achieved. The PQMA type power quality monitoring instrument can comprehensively monitor, summarize, and record various information of power quality. It has the characteristics of stable operation, high measurement accuracy, large storage capacity, rich data information, strong communication function, and easy installation and use. It can be operated as a single unit or networked to form a power quality monitoring system. PQMA can accurately record the power quality status in real time, effectively monitor harmonic users, and is suitable for online monitoring of power quality for power enterprises and power users. Can replace imported similar products.
