Calibration

Pwer Meter Calibration

Traceability of wide-bandwidth power meter

Calibration method for the working standard

  1. Voltage calibration
  2. Current calibration
  3. Phase angle measurement of the capacitor
  • Preparing some capacitors each frequency (50/ 60/ 400/ 1k/ 2k/ 5k / 10k/ 20k/ 50k/ 100k/ 200k/ 500kHz)
  • Measuring admittance (Conductance-G and susceptance-X) of the capacitor using precision LCR meter
  • Calculating the phase angle of the capacitor
  1. Power calibration at PF=0
    (It measures Internal phase difference between voltage and current input circuit.)
  2. Power calibration at PF=1

Calibration Method for working standard at PF=0
