Loop control with F3 Fault
Figure 7-10. Loop Control with F3 Fault
Step1 : At F3 location, when Permanent Fault occurs, RC1 conducts reclosing cycle.
AS3 counts
“SEC Operate Cnt”
when Dead line Voltage after sensing a Fault.
When RC1 trips three times, it reaches
“SEC Operate Cnt”
set value (3). Then F3
location is disconnected after
“SEC Oper’ TD”
Timer is finished.
AS1, AS2 are not operating because that they did not sense the fault.
Step2 : AS3 is opened and RC1 is closed after three times of reclosing.
RC1 is closed after AS3 disconnect F3 location, and keep the rest of line normal.
Step3 : After removing the Fault, manually (local or remote) close AS3 and recover the live line.
