Conclusions
The use of three-terminal measuring cells and of the contact and contactless measurement method related with them increases considerably the accuracy of determining the dielectric constant of solid and liquid dielectrics (by a factor of 3–10 in comparison with GOST 13671-68). The maximum accuracy for solid specimens is attained with the use of liquid immersion media.
These comments should be taken into consideration when working out new standards on methods of determining the characteristics of dielectrics in the 50 Hz-1 MHz frequency range.
