6.2.4.6 BROKEN CONDUCTOR
F650 units incorporate three Broken Conductor elements for special applications that may require different timing steps or
levels for alarm or trip purposes.
The green LED will light up when the pickup or trip (operation) of each of the three available functions is activated. The
three of them are identical and can be configured separately.
These functions compare the negative and positive sequence current levels per phase. If this magnitude exceeds a
programmable threshold and is maintained for a programmable time delay, a tripping output will be issued. If a pickup or
operation is produced, the corresponding LED in this screen will light up.
This screen can be accessed at Actual> Status > Control Elements > Broken Conductor, and it includes the following
