Beschreibung
Zusammenfassung:	FIELD: electricity.SUBSTANCE: according to the monitoring method of normal and emergency modes of electrical systems, the instantaneous voltage and current values are recorded at each sampling interval after a quarter of the network frequency period at the time when the voltage polarities shown by the resistor and the capacitor of the series RLC circuit are reversed.EFFECT: improved measuring accuracy.3 dwg Использование: в области электротехники. Технический результат - повышение точности измерения. Согласно способу для контроля нормальных и аварийных режимов электрических систем фиксируют мгновенные значения напряжений и токов на каждом интервале дискретизации через четверть периода частоты сети в моменты смены полярностей напряжений на резисторе и конденсаторе последовательной RC-цепи. 3 ил.
