COUNTER OF VOLTAGE SPIKES AND DIPS WITH CRITICAL PARAMETERS Russian patent published in 2002 - IPC

Abstract RU 2183047 C2

FIELD: data-metering and computer engineering. SUBSTANCE: counter is designed for counting voltage spikes or dips exceeding various analysis levels for time longer than specified critical values. Counter has ac-to-dc voltage converter, subtraction unit, reference-voltage source, inverter, switch, n comparators, where n is number of amplitude modulus analysis levels of voltage spikes or dips, n + 1 one-shot multivibrators, n D flip-flops, OR gate, and meter. EFFECT: simplified design, facilitated operation and maintenance. 5 dwg
