Power Quality Analyzer's Basic Function:

• Test function:

Real-time waveform display (4-channel voltage/4-channel current); true RMS voltage and current; voltage DC component; current and voltage peak value; maximum/minimum value of current and voltage within a period of time; phasor diagram display; each phase Harmonic measurement, up to the 50th harmonic; bar graph showing the harmonic ratio of current and voltage of each phase; calculation of total harmonic distortion (THD); active/reactive/apparent power value and total value of each phase ; Active/reactive/apparent energy value and total value of each phase; transformer K factor calculation; COSφ displacement power factor (DPF) and power factor (PF) calculation; flicker calculation; three-phase unbalance calculation (voltage and current )

• Transient capture function

Monitoring instantaneous change of power grid voltage current parameters, including the voltage current fluctu-ations, voltage current surge, sag and short supply interruption, temporary overvoltage, impact current and Cur-rent voltage instantaneous distortion. Instruments can store 150 sets of transient waveform at the same time.

• Starting current monitoring

Monitoring surge current of line and the startup current when electrical equipment is starting, help to correctly design capacity. Can be display the RMS rising / falling curve In the startup process, the envelope curve of startup current, waveform of 4 channels current and 4 channels voltage. Recording about 100s after trigger, storage the current /voltage instantaneous and waveform curve of each cycle in 100s.

• Trend chart recording and storing function

Store all the test parameters of basic test functions (Urms, Uthd, Ucf, Uunb, Hz, Vrms, Vthd, Vcf, Vunb, PST, Arms, Athd, Acf, Aunb, KF,W, VAR, VA, PF, COSφ, TANφ),50 voltage harmonics, 50 current harmonics. And create the trend curve. Record data for a long time according to need(concurrent selection 20 parameters to record data for once every five seconds, you can record about 300 days.).

• Alarm function

Set the limit values according to need, monitoring the values whether overshoot, if overshoot will generate an alarm log, such as: voltage, current, unbalance, harmonic ratio, frequency, active power, total harmonic distor-tion. You can configure 40 different alarms, each group can set different monitoring parameters (including 50 harmonics, total of 123 different parameters) and limit values, also can set the shortest time of overshoot. The log can contain up to 12,800 alarms.

• Snapshot function

Any screen can be saved (screen snapshot), at the same time automatically records the time and test mode. Such as can save voltage and current waveform, harmonic bar chart, phasor diagram etc. It can save a maximum of 60 screen snapshot.

• Communication function

Communicate with computer via USB; Monitoring software can display waveform of power quality analysis, read of the transient waveform, trend chart recording, alarm log, screenshots, and display on the computer.

• Setting function

The user can configuration of the time and date, configuration of the screen contrast and brightness, definition of each phase curve colors’.

Choice of type of connection to the net work.

Configuration of the type of the current sensors and voltage ratios.
