METHOD OF COMPENSATION OF CAPACITIVE SHORT-CIRCUIT CURRENTS TO GROUND Russian patent published in 1994 - IPC

Abstract RU 2025860 C1

FIELD: electrical engineering. SUBSTANCE: method is based use of reactor with magnetization for protection against single-phase fault to ground. In case of single-phase fault to ground two good phases are chosen, voltage of these phases is rectified and is used to feed magnetization windings of reactor. EFFECT: improved reliability of protection. 2 dwg
