Generalized bridge network for dielectric measurements

RECENT experience with bridges for the determination of power factor and dielectric constant of small oil samples over a range of frequency has indicated the desirability of improving their characteristics. These improvements or developments have to do principally with changes in circuit arrangements, a generalized representation of the bridge network in terms of controllable impedances, an increased sensitivity inherent in the bridge itself, and an effective means for controlling the influence of inherent impedances extraneous to the bridge measuring arms on the accuracy, precision, and dependency of the bridge measurements and balances.
