☆ Calibrate Single Three Phase Power Source /Meter

TD3310 Three-phase Multifunction Standard Meter Calibrate Single Three Phase Power Source /Meter

• The TD3310 three-phase power/energy has an optimal measurement uncertainty of Class 0.01.

• Suitable for calibrating single/three-phase power sources with class 0.02 and below, power meters/standard energy meters (with stable power sources).

• Suitable for calibrating single/three-phase voltage standard sources and voltage standard meters of class 0.02 and below (with stable voltage sources).

• Suitable for calibrating single/three-phase current standard sources and current standard meters of class 0.02 and below (with stable current sources).

☆Comprehensive Analysis of AC Power

S/N	Function
	The measuring channel has the function of oscilloscope, which can display the waveform of the measured power in real time.
	Accurately measure the phase between the voltage and current of each phase, and visually display it through the form of phasor diagram.
	Two types of harmonic distortion, THD/T (harmonic relative to full wave) and THD/F (harmonic relative to fundamental wave), are calculated.
	The amplitude (RMS), content (%) and phase of the 2nd ~ 127th harmonic wave of each phase voltage or current can be analyzed in real time.； It is used to check whether the harmonic content and phase of complex waveform output of R46 device meet the requirements of the regulation.
	The spectrum of each harmonic is visually displayed in the form of a bar chart (the fundamental wave is 100%).
☆Data Statistical Analysis Function

S/N	Function
	Statistical analysis of data: calculate the maximum value (Max), minimum value (Min), peak-peak value (P-P), average value (Avg), standard variance (S.dev), etc.
	Power stability test: In the test cycle, real-time plot the curve of power change with time.
	Normal distribution histogram: Displays the distribution of the collected power within a test period.
	Power stability test: According to the algorithm of JJG 597-2005 "Verification Regulation of AC Watt-hour Meter Verification Device", the output power stability of the inspected electric energy device can be calculated automatically.
