When it is interfered or contaminated, grid power quality can’t reach the national standards,
so it has to be targeted on the grid power quality improvement. To understand the actual situation
of power quality, you must have the appropriate equipment to test and analysis the actual situation.
Counter the domestic condition, our company developed the professional power quality analysis
instrument, which is suitable for the country. The following will illustrate the specific
performances, parameters, methods of use on the power quality analyzer in detail.
I Functions and Features
1. The instrument is designed as a high-precision test equipment to detect grid waveform
distortion occurrence, the harmonic content , voltage fluctuations and flicker and phase imbalance
of power quality problems; It also includes electrical parameters testing, vector analysis functions.
2. It can accurately measure a variety of electrical parameters, such as voltage, current, active
power, reactive power, phase angle, power factor, frequency, etc.
3. It can display the vector diagram of the measured voltage and current , by analyzing which
users can judge if the metering device wiring is correct or not.
4. Current is measured by using the clamp transformers. You can easily and securely do the
measurement, because of the use of clamp current transformers, without connecting the current
loop. Depending on the user's measurement range, you can be equipped with different range of
clamps.
5. Measurement and analysis of the AC power quality from the utility grid to client can be
done easily, its measurement and analysis: frequency deviation, voltage deviation, voltage
fluctuations, flicker, three-phase voltage unbalance factor and harmonic.
6. It can display single-phase voltage, current waveform and can display three-phase voltage
and current waveform at the same time.
7. All testing interface is functioned with a screen lock feature to facilitate reading and
analysis of user data.
8. Load fluctuations monitoring: It can measure and analysis fluctuations on the utility grid
