FIELD: data measurement and computing engineering; power engineering for checking electrical energy parameters for compliance with State Standard. SUBSTANCE: analyzer has ac-to-dc voltage changer, analog-to-digital converter, commutator, two-position and multiposition selector switches, coder, switch, first, second, and third NAND gates first, second, third, and fourth counters, sample pulse generator, clock generator, memory unit, display unit, first and second flip-flops, decoder, NOT gate. EFFECT: improved reliability due to eliminating distortion of stored statistical information in memory unit polling mode and simplified design due to dispensing with register and two one-shot multivibrators. |
