Power quality monitoring仪Features:

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 quantity system，Stronger anti-interference ability;High precision:Reference algorithms are used for harmonics and three-phase imbalance, without approximate calculations and with high accuracyA/D（sixteenBit), simultaneous sampling, collection rate12.8 kHz；Strong software functionality:adoptDSP+ARM+CPLD The kernel has fast processing speed and rich software functions, making it suitable for complex testing and data processing work, greatly improving testing efficiency and level.

2. Multiple testing parameters:System frequency and grid harmonics2-50Subharmonics, three-phase voltage imbalance, voltage deviation, effective value and true effective value of voltage fundamental wave, effective value and true effective value of current fundamental wave; Split phase active power, reactive power, apparent power, power factor; Total active power, reactive power, apparent power, power factor; Split phase active energy, reactive energy, total active energy, and reactive energy; Voltage surges, current surges, etc.Real time harmonic data judgment:The instrument has internal harmonic national standard values, which can accurately and in real-time determine whether the current voltage harmonic and current harmonic data tested are normal or exceeding the standard.

3. Communication interface:Power quality tester provided2个USBInterface, a host port used to store data toUDisk, a device port that communicates with a laptop to achieve data transmission and analysis;AC Power Quality MonitorData graphic display:five point sevenThe inch blue LCD screen can complete spectrum, waveform, real-time data display, vector analysis, wiring discrimination, and is intuitive and clear.
