6.2.3.2 PHASE CURRENT
This screen shows the pickup and trip for all phase instantaneous and time overcurrent elements in the W650 and block
and operation signals provided by the phase directional units. Any of these two events of any phase element will light up
the corresponding LED in this screen, and it will remain lit as the associated function remains in pickup or operation. All the
values are provided for phases and total as shown on the table below.
This screen is accessed in menu: Actual> Status > Protection > Phase Current, and includes the following signaling
LEDs:
