Abstract : Pitfalls in the measurement of nonlinear dielectrics are considered and it is shown that to obtain meaningful results, the method of measurement must be investigated. In this report, the dielectric constant of nonlinear dielectrics is discussed as a function of the electric field strength while the other properties of the dielectric material are applicable to the methods employed. A comparison is made of the results of measurements of the capacitance of 60 Hz, 400 Hz, and 1 kHz for three samples prepared by different processes and containing different buffering materials: (1) a commercial BaTiO3 capacitor, (2) a No. 832 capacitor (thick), and (3) an approximately 100% BaTiO3 capacitor (thin). A comparison of their maximum voltage and field strength is also given. (Authr)
