CHAPTER 5: SETTINGS SYSTEM SETUP
D30 LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL 5-147
5
The breaker control element contains the auxiliary logic for status and serves as the interface for opening and closing of a
circuit breaker from protection, autoreclose, SCADA, or through the front panel interface. The breaker control element can
be used to create interlocking functionality. For greater security in determination of the breaker position, both the 52/a and
52/b auxiliary contacts are used with reporting of the discrepancy between them.
To use this element, configure the contact outputs that trip and close the breaker to use FlexLogic operands BREAKER 1 OFF
CMD (or BREAKER 1 TRIP A/B/C in the case of single-pole tripping) and BREAKER 1 ON CMD, and configure the breaker control
element inputs as described here.
