Functional features
1. This instrument is a high-precision testing instruments, specially used to detect the power quality problems in the power network such as waveform distortion, harmonic content, voltage fluctuation and flicker, and three-phase unbalance. At the same time, it also has the function of electric parameter test and vector analysis.
2. Can accurately measure voltage, current, active power, reactive power, phase angle, power factor, frequency also other electrical parameters.
3. Can display vector diagram of voltage and current which been tested, and user can get the correct wiring of metering equipment by analyzing the vector diagram.
4. The current is measured by split-core type current transformer. it is convenient and safe to measure, since the operator does not need to disconnect the current loop when measuring with the current transfo rmer. The clamp table can be selected according to the user's different measuring range.
5. It can measure and analyze the ac power quality supplied by the utility network to the client, includes frequency deviation, voltage deviation, voltage fluctuation, flicker, three-phase voltage allowable unbalance and power network harmonic.
6. It can display single - phase voltage and current waveform, and also can display three - phase voltage, current waveformat same time.
7. All test interfaces have a screen lock for userto read and analyse test data.
8. Load fluctuation monitoring: measure and analyze the fluctuation of power quality caused by various electrical equipment in different operation states.Periodically record and store the variation trend of voltage, current, active power, reactive power, apparent power, frequency, phase and other power paramet ers.
9. Dynamically monitor the adjustment and operation process of power equipment to help users solve the problems in the adjustment and operation process of power equipment.
10. Can test and analyze the dynamic parameters of reactive power compensation and filter device in power system,and make quantitative evaluation on its function and technical index.
11. Can set different storage interval time, and also can continuously store data at set interval time.
12. Large capacity data storage, storage interval time is adjustable from 5 seconds to 5 minutes. It can be stored continuously for more than 18 months at a time interval of 1 minute, which can satisfy the needs of long-term monitoring test sites.
