APPARATUS AND METHOD FOR ARC FLASH PROTECTION IN ELECTRICAL POWER SYSTEMS

摘要

A circuit (30) for use in an electrical system (2) having at least one of a shorting device (14) or a first circuit interrupter (10) and having a second circuit interrupter (12). The circuit is configured to: receive a logical signal (26) indicative of an arcing event related to the electrical system; receive another logical signal (28) indicative of operation of the second circuit interrupter (12); and selectively operate or not operate the at least one of a shorting device or a first circuit interrupter dependent on at least one of the logical signals (26, 28).
