A review of dielectric measurements

This review of dielectric measurements is confined to the measurement of the complex dielectric constant of dielectrics, with no consideration whatever for the measurement of dielectric strength. Only measurement technique will be considered, with no reference to specific dielectric properties except as their magnitude and variation directly affect the technique. The conditions under which measurements must be made will be considered in some detail. These conditions are frequency, temperature, pressure and voltage gradient, together with the shape of the specimen and the accuracy of the measurement.
