METHOD FOR PROTECTING CONTROLLED REACTOR AGAINST INTERNAL SHORT CIRCUITS Russian patent published in 1998 - IPC

Abstract RU 2124259 C1

FIELD: electrical engineering. SUBSTANCE: method involves checking voltage across equalized ac current points of reactor magnetizing coils connected to external DC power supply; when commercial- frequency voltage is built up between these points, signal is sent for reactor switching off. EFFECT: improved sensitivity and simplified protection of controlled reactor against internal short circuits. 1 dwg
