The paper considers two- and three- component electrode systems in contact electric field sensors. The design of electrode systems optimally meets the requirements for devices to be set on mobile platforms for specific needs. Electrode systems are characterized by minimum of electrodes used: the number of electrodes outnumbers the registered components of the electric field vector by one. Nearly identical flow conditions in the vicinity of electrodes, geometric symmetry of the electrode system, and electric symmetry of measuring channels are provided. The analytical expressions for the elements of the equivalent circuit of the sensor are obtained, and the pre-processing circuits of useful signals are offered.
