An automatic-reclosing circuit-breaker which opens and remains open after only a single reclosing operation if a fault persists, is provided with means responsive to a predetermined plurality of opening operations to prevent further reclosure of the circuit-breaker whether or not a fault persists. ...
three phase auto-reclosure Application The REXA 101 reclosing relay is intended REXA 101 provides six built-in alternative for transmission or subtransmission lines to re-closing programs which can easily be restore service when a circuit breaker is changed after installation in case the operat- tri...
But the system may fail to maintain stability even after a successful reclosure for high values of prefault power transfer. A sequential switching scheme employing three fast-acting isolators in addition to the autoreclosing circuit breaker is suggested. It improves the transient stability limit of...
