1. Measure three-phase voltage, current, active power, reactive power, apparent power, power factor, frequency, running time and other basic functions. 2.Display the numerical steady-state three-phase voltage, three-phase current, active power, reactive power, apparent power, power factor, frequency, operation time ,sine waveform and phase sequence; transient curve of test voltage and frequency, 2~21times harmonic analysis of 50Hz sinusoidal waveform, report harmonic component, distortion rate ; 3.Voltage, frequency tuning test, wave test, transient test , automatic test the maximum, minimum value of voltage and current and recover time; 4. Automatically generate a variety of charts, testing reports, and change the format, sign, if you need ; Test report can be search by time, model and other condition, minimum resolution time of steady state recording is 1second. 5. System can automatically load in strict accordance with the provisions of the national army standards from 0, 25%, 50%, 75%, 85%, 90%, 100%, 110% (according to the customer demand)100%, 90%, 85%, 75%, 50%, 25%, 0 when the user input the rate power and testing time, and the display instrument will show the change of V, I, KW, Hz .The test point can also be manually set by the user ; 6. you can sudden load, sudden unload with any percentage of load power;
