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.
