METHOD FOR PROTECTING CONTROLLED REACTOR AGAINST INTERNAL SHORT CIRCUITS |
摘要 |
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 dwgc
