GF335 three phase and harmonics power quality analyzer
Introduction
GF335 three phase and harmonics power quality analyzer is suitable
for power company, technical supervision department, industrial,
mining, petroleum as well as chemical, home appliances and
manufacturing enterprises.
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 of 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) Measuring harmonics: measure/display voltage and current
waveforms and harmonic bar graph.
(5) Calibrator meter: load calibration of various single phase and
three phase energy meters.
(6) Vector analysis: based on the voltage, current and phase error,
display vector graphics.
Features
- Ultra-compact design, handheld, small size, light weight.
- The usage of multi-channel power supply, AC power supply can also
be rechargeable battery-powered machine.
- High accuracy instrument, good stability and wide range of voltage
monitoring 0-1200V, current 1mA - 20A.
- It can be divided into direct current clamp measurements and
precision measurements.
- It can measure three phase voltage, current, active power, reactive
power, power factor, frequency, phase, etc.
- Showing the AC waveform, vector diagram and determining the 3P3W
connection errors.
- It can measure harmonics ration from 2nd to 64th and the harmonic
analysis.
- The measured data can record, query and upload print.
- Instrument calibration by using software to facilitate the
correction instrument variation.
