Power quality monitoringdeviceThe main functions and characteristics of:
1. Reliable:The voltage input adopts a high-voltage isolation module(2000VResponse time ≤2μSThe current input adopts AC clamp(0~50kHz, 0~5Arms)Isolate the input signal from the measurement system. This not only makesRT-PQ1100Reliable and convenient in use, and greatly improvedRT-PQ1100Its anti-interference ability.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 for continuous operation without external power supply8Hours.
2. High precision:Conforming to national standardsALevel instrument requirements. Reference algorithms are used for harmonics and three-phase imbalance, without approximate calculations and with high accuracyA/DSimultaneous sampling, collection rate12.8 kHz.Strong functionality:adoptDSP+ARM+CPLDKernel, fast processing speed, rich functionality, enabling其Suitable for complex testing and data processing work, greatly improving testing efficiency and level.
3. Communication interface:provideUSBInterface for easy storage of data toUCommunicate and transmit data with laptops;Real time printing:Equipped with a micro thermal printer, it can print real-time on-site test data at any time.Multiple testing parameters:System frequency, grid harmonics, three-phase voltage imbalance, voltage deviation, fundamental effective value and true effective value of voltage, fundamental effective value and true effective value of current, fundamental active power, active power, fundamental apparent power2-50The parameters specified in the five major national standards for power quality, such as subharmonics and true power factor.
4. Real time harmonic data judgment:Real time judgment of whether the current voltage harmonic and current harmonic data tested are normal or exceeding the standard.Background management analysis:Power quality monitoring deviceManagement analysis is a set of backend management analysis for power quality, running onWIN9X/2000/XP/NT The operating system has a user-friendly interface, with graphical and curve analysis functions, and is equipped with relevant information query, national standard query, and other content.
