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

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.

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.).

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 distortion. 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.

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.

Communicate with computer via USB; Monitoring software can display waveform of power quality analysis, read of the tran
