The paper presents a description of three levels of visual meta-language developed for hybrid intelligent systems of electrical networks management: 1) tasks and problems; 2) patterns for expert reasoning; 3) integrated models of collective intelligence. Visual metalanguage qualitatively changes the work mode of a managed subject, allowing them immediately to recognize the problematic situation and «see» its solution without logical inferences.

The article offers a new, non-contact method of measuring the specific electrical resistance of liquid metals in the high-temperature range, which is exceptionally simple. The essence of the method is the measurement of the electromotive force induced by a high-frequency electromagnetic field in two circuits of different diameters placed coaxially in the middle of a cylindrical sample, which is a thin-walled ampoule filled with some low-melting metal. The authors substantiate the feasibility of a contactless method for measuring the specific electric conductivity of both solid and liquid metals in the hightemperature range. Result-processing methodology is given as well as the recommendations on the optimal geometry of the contours and the sample for increasing the measurement accuracy.
