BE1-CDS220 Reporting and Alarm Functions 6-35
(including targets) won't operate again until the pickup and logic trigger expressions return to a FALSE
state to enable another trigger.
Breaker Operate Time. This line reports the breaker trip time from the breaker monitoring and alarm
function. This is the time measured from when the breaker is tripped until the fast-dropout current detector
function detects that the arc has been extinguished. Refer to Figure 6-9 and Table 6-11, call-out D.
Oscillographic Reports. This line reports the number of oscillographic records that are stored in memory
for this fault report. Refer to Figure 6-9 and Table 6-11, call-out E. Recording of oscillographic records is
described in the Oscillographic Records subsection.
IA1, IA2, IB1, IB2, IC1, IC2, IN1, IN2, IQ1, IQ2, IG. These lines report the current magnitudes and angles
measured two power system cycles immediately following the trip trigger. If the fault is cleared prior to the
relay tripping, the recorded fault currents are for the power system cycle two cycles prior to the end of the
fault. Refer to Figure 6-9 and Table 6-11, call-out F.
Retrieving Fault Report Information from the Relay
Fault Summary Directory Report. The fault reporting function provides a directory of fault summary
reports that lists the number assigned to the fault summary report along with the date and time of the
fault, the event type, and the total number of oscillography records stored in memory for that event. The
event number is important because it is required to retrieve information about that event from the relay.
This directory report can be accessed by using the RF command.
RF Command
Purpose:
Read/Reset Fault Report Data
Syntax: RF[-n/NEW][=0/TRIG] where n=record # or NEW = new records

New Faults Counter. One line of the fault summary directory report contains the new faults counter. The
new faults counter tracks how many new fault reports have been recorded since the new faults counter
was reset to 0. This counter provides a way to check the fault information and then reset the new faults
counter. Then, the next time that the relay is checked, it's easy to determine if any fault reports have been
entered. Resetting the new faults counter is achieved using the RF-NEW=0 command. Write access to
Reports must be gained to reset the new faults counter through the communication ports. The new faults
counter can also be viewed at HMI Screen 4.1, \REPRT\FAULT. The new faults counter cannot be reset
at the HMI.
Fault Summary Reports. Individual fault summary reports can be retrieved using the RF-n command,
where n represents the number assigned to the fault summary report. To obtain the most recent report,
use RF-NEW. If additional detail is desired, Sequence of Events Recorder data and Oscillographic data
can be obtained for the faults also. This is discussed in greater detail later in this section.
