Patent number: 8737030Abstract: A power distribution system includes a first circuit protection device and a second circuit protection device coupled to the first circuit protection device downstream of the first circuit protection device. The second circuit protection device includes a trip mechanism configured to interrupt a current flowing through the second circuit protection device, and a trip unit operatively coupled to the trip mechanism. The trip mechanism is configured to determine, for the second circuit protection device, a protective threshold and a blocking threshold that is lower than the protective threshold, transmit a forward blocking signal to the first circuit protection device upon a determination that the current exceeds the blocking threshold, and generate a reverse blocking signal upon a determination that the current exceeds the protective threshold.Type: GrantFiled: September 14, 2012Date of Patent: May 27, 2014Assignee: General Electric CompanyInventor: Marcelo Esteban Valdes
