Abstract

FIELD: electromeasuring equipment. SUBSTANCE: aim is to increase accuracy of fault to earth direction determination in AERIAL distribution networks with insulated neutral due to measurement of loading zero sequence current before fault to earth and current of zero sequence in the form of sum of current of loading and fault to earth after phase fault to earth took place with following compensation of loading current components with simultaneous determination of power sign. EFFECT: increased accuracy of fault to earth direction determination in AERIAL distribution networks with insulated neutral.

Изобретение относится к электроизмерительной технике. Цель изобpетения - повышение точности определения направления замыкания на землю в воздушных распределительных сетях с изолированной нейтралью за счет измерения тока нулевой последовательности нагрузки до замыкания на землю и тока нулевой последовательности в виде суммы тока нагрузки и замыкания на землю после возникновения замыкания фазы на землю с последующей компенсацией составляющих тока нагрузки с одновременным определением знака мощности.The invention relates to electrical engineering. The purpose of the invention is to increase the accuracy of determining the direction of the earth fault in air distribution networks with isolated neutral by measuring the zero sequence current load before the earth fault and the zero sequence current as the sum of the load current and earth fault after the occurrence of a phase to earth fault followed by compensation components of the load current with the simultaneous determination of the sign of power.
