PQ8000 power quality online monitoring and measuring device adopts high speed and high performance DSP, integrated into harmonic analysis�pflicker measurement�ppower measurement�punbalance voltage measurement and fault record, and record steady-state data and transient data, deeply find out the cause of every process. Quick collection�paccurate analysis of every electrical parameter, monitoring every data of power quality, integrated with communication interface, and combine with PQS power quality monitoring software, constitute the power quality monitoring system.

Technical feature

•Harmonic analysis
Monitoring network every harmonic component in 50 times, including 2��50 times harmonic distortion rate�ptotal harmonic distortion rate�p even total harmonic distortion rate�podd total harmonic distortion rate�pharmonic phase angle and inter-harmonic. It met the international GB/T14549 and IEC6100-4-7 to the utility grid harmonic testing requirements.
•Flicker analysis
Because the voltage changing cause flicker such as arc furnace �pelectric welding machine, etc. can easy to make eye fatigue�pdiscomfort�pand even the mood be agitated. PQ8000 have voltage flicker detection function, accord with EN50160�pIEC61000-4-15 and GB/T12326 standard.
•Voltage fluctuation and fault record
This device can capture all of voltage and current waveform to analysis interference source, so as to capture a miner change in the voltage waveform.
•Component measurement and voltage unbalance degree analysis�pmonitoring and recording of power system frequency fluctuation
Pq8000 can measure unbalance degree�pzero sequence�ppositive sequence�pnegative sequence of amplitude and phase from voltage and current. Display phase diagram of the voltage and current. PQ8000's frequency measure accuracy is 0.001 Hz, frequency range is from 20 Hz to 80 Hz, this device can implement on-line monitoring of power system frequency, when frequency cross the maximum value that the device will alarm.
•Exceeding measurement of power quality�pdata record and event process record
This device can be continuously detect whether the power quality conform to the standard, can set different standard condition via software, enable exceeding electrical parameter statistics and record corresponding superscalar, temporal resolution can be reach to the 1 ms,  PQ8000 configure with 8 GB  memory card, which used to store energy data and fault waveform.
