data-measuring, computer, and electrical engineering. SUBSTANCE: analyzer designed for producing families of time distribution functions to analyze beyond- specified intervals of voltage surge and dip levels at various voltage fluctuations as well as for checking power characteristics at transient voltages in industrial power networks and for estimating impact of these voltages on various pieces of electrical equipment has input terminal, ac-to-dc voltage converter, high- and low-frequency filters, modulus generators, null detectors, register, analog-to-digital converter, n analog comparators, where n is number of levels for analyzing surge amplitude and amount of voltage dip, n + 1 binary counters, multichannel switch, digital memory units, digital comparator, AND gate, OR gate, flip-flop, level distributor, square- wave generators, binary-decimal counter, and one-shot multivibrator. EFFECT: enlarged functional capabilities due to ability of analyzing transient random processes. 2 cl, 3 dwg
