Description
GF334 Global wholesale High Accuracy Three Phase Power Analyzer
It is suitable for power companies and technical stupervision departments. Industrial, mining, petroleum and chemicals, home appliances and manufacturing enterprises are in the suitable fields.
Functions
1. Measuring energy consumption values - the precise timing measurements of electrical equipment for short-term energy consumption; energy resolution: milli-watts; time resolution: milli-second; they are difficult to available for common instrument of power. The functions are used by pumping, cranes, air conditioning and other equipment in a work cycle connected power consumption.
2. The value of the measurement process- it can be recorded and tested continuously voltage, current, active power,reactive power and other electrical parameter values and curves in a dynamic process and graphically display.
3. To measure the instantaneous values - including the exchange parameters: U, I, P, Q, PF, phase angle, frequency, harmonics, etc.
4. Measurement of harmonics - measurement / display voltage and current waveforms and harmonic bar graph.
5. Check Meter - real live load calibration of various single-phase, three-phase energy meters.
6. Vector analysis - based on the voltage, current, phase error of judgment wiring, display vector graphics.
Features
1. Ultra-compact design, handheld, small size, light weight
2. The usage of multi-channel power supply, AC power supply can also be rechargeable battery-powered machine
3. High accuracy instrument, good stability, and wide range of voltage monitoring 0-1200V, current 1mA - 20A
4. It can be divided into direct current clamp measurements and precision measurements
5. It can measure three-phase voltage, current, active power, reactive power, power factor, frequency, phase, etc
6. Showing the AC waveform, vector diagram and determining the three-phase three-wire connection errors
7. It can measure harmonic content from 2 to 64 and the harmonic analysis
8. The measured data can record, query and upload print
9. Instrument calibration by using software to facilitate the correction instrument variation
