Abstract

It is developed a method for measuring of dielectric permittivity of liquid dielectrics. High accuracy and reliability of the method is provided by definite hardware realization; it is used resonance-bridge method; to provide high stability of measuring SHF signal frequency there is used self-excited oscillator on a basis of active running wave resonator.
