Measurement of High-Values Quality Factor of Capacitive Objects by the Direct Method Using a Special Calibration of Impedance Meter

Abstract: The problem of the quality factor measurement of more than 1000 is considered. The maximum values of the capacitive objects Q-factor are indicated, at which modern impedance meters give a satisfactory error. It is shown that the proposed approach to the calibration of impedance meters increases the upper limit of the Q-factor measurement range by two orders of magnitude while maintaining an acceptable measurement error.
