Distribution line switchgear control employing a precision rectifier

摘要: A distribution line switchgear control which is particularly suitable for use with recloser requires small amounts of power from the operation. The most usefully powered continued operation by current provided through a source transformer and includes multiple capacitors are arranged in cascaded supply having plurality isolated stages. precisely monitored sensing transformers causes to trip, reclose lockout, as appropriate protect electricity. Inhibit circuits prevent issuing trip signal, unless sufficient energy exists portion supply. variety volatile timers counters enable cause lockout. Initialization circuits, supply, non-volatile state memory responsive close lockout signals control, initialization elements inappropriate signals.
