Power Quality, in a general sense, refers to high-quality power supply, including voltage quality, current quality, power supply quality, and electricity consumption quality.
Multi functional instrument is a multifunctional smart meter with programmable measurement, display, digital communication, and power pulse transmission output functions. It can complete power measurement, power metering, data display, acquisition, and transmission, and can be widely used in substation automation, distribution automation, intelligent buildings, internal power measurement, management, and assessment of enterprises. The measurement accuracy is 0.5 level, and the MODBUS-RTU communication protocol is used to achieve LED on-site display and remote RS-485 digital interface communication.
This series of products has a performance price ratio of *, which can directly replace conventional power transmitters, measurement indicators, energy meters, and related auxiliary units. As an intelligent and digital front-end acquisition component for the power grid, the PZ568E/Z series multifunctional network power monitoring instrument has been widely used in various control systems, SCADA systems, energy management systems, substation automation, distribution network automation, community power monitoring, industrial automation, intelligent buildings, intelligent distribution panels, and switchgear. It has the advantages of easy installation, simple wiring, easy maintenance, small engineering quantity, programmable input parameters on site, and can complete the networking of different PLC and industrial control computer communication software in the industry. The product complies with GB/T 22264.1-2008 and GB/T13978-2008.
The power quality analyzer is positioned as a multifunctional, portable measurement and analysis instrument It can monitor conventional power quality information such as voltage, current, and frequency, as well as perform harmonic analysis on signals, draw THD curves, detect voltage three-phase imbalance, and detect amplitude modulation waves and flicker In terms of hardware, a portable industrial control computer is adopted, which is embedded with a data acquisition card, a signal preprocessing card, and multiple voltage and current transformers This structure makes it have the characteristics of simple hardware circuit, easy implementation, small overall size, and easy portability In terms of software, a graphical interface and algorithm software with virtual instrument style was developed using Visual C++5.0, and a virtual device driver program was developed to respond to Windows 95 interrupts for data collection, integrating hardware and software organically In terms of detection methods, synchronous sampling technology is adopted for the detection of voltage and current signals, thereby eliminating the phenomenon of 'leakage error' that occurs during FFT transformation in conventional sampling; Especially in the detection of amplitude modulated waves and flicker
