Electrical Power Analyzer

1.Functional features of Electrical Power Analyzer

Electrical Power Analyzer is used to understand the actual power quality of the power grid, and master the power quality and load of the measured point.

1.Multi-channel measurement: 4 voltage channels and 4 current channels are measured simultaneously.

2.Electrical parameter measurement: The voltage amplitude, current amplitude, phase, frequency, active power, reactive power, power factor and other numbers can be measured simultaneously;

3.The voltage harmonic and current harmonic content can be measured 2-64 times;

4.The total harmonic distortion rate can be measured;

5.It can measure and short-term flicker (PST), long-term flicker (PLT), and voltage fluctuations;

6.It can measure positive sequence voltage, negative sequence voltage, zero sequence voltage, and voltage imbalance;

7.It can measure positive sequence current, negative sequence current, zero sequence current, current imbalance;

8.Transient parameter measurement function, with voltage surge and drop event recording function, and automatically starts the wave recording function to record the time of the occurrence of the event and the actual waveform of the five cycles before and after;

9.It has oscilloscope function, which can display the voltage and current magnitude and distortion in real time, and can display the voltage and current waveform on the instrument;

10.The hexagonal diagram display function can perform vector analysis of the metering circuit and the protection device circuit, and conduct wrong wiring checks of the metering device; in the three-phase and three-wire wiring mode, 48 wiring methods can be automatically judged; the automatic calculation function of the power supply is convenient for users who have problems with wiring to calculate the power supply.

11.The large clamp meter can be used to measure the ratio and angle difference of low-voltage current transformers;

12.Harmonic content can be displayed in the form of a bar chart, with good visual effect;

13.Built-in large-capacity data memory (storage interval is 1 second-1000 minutes optional) can be continuously stored for 18 months at a time interval of 1 minute;

14.10-inch large-screen color LCD screen display 1280×800;

15.The touch operation of the capacitive screen is similar to that of the operation of tablets and smartphones, making it easy to learn;

16.Support mouse operation and adapt to operators with different habits;

17.When measuring harmonics, you can automatically determine whether the harmonic content exceeds the standard according to the national standard and give a prompt, which is clear at a glance;

18.The national standard query function of harmonic content ratio can query the allowed values of the national standard;

19.It has a frequency measurement range of 42.5Hz-69Hz, and can measure 50 and 60 power systems.

20.Data can be stored in USB flash drive for historical query.

21.It can be equipped with special data analysis and management software to analyze and process the test results, and can grasp the periodic changes of the power quality and load of the measured points, and play an irreplaceable role in understanding the user's power quality and taking corresponding treatment measures;

22.The analysis software can generate professional power quality analysis reports in accordance with the national standard requirements;

23.The instrument is small in size, light in weight and easy to carry;

24.Built-in high-performance lithium-ion battery, which automatically enters power-saving mode, allows the instrument to work continuously for more than 10 hours without an external power supply, making it convenient for on-site testing;
