The selective curves employ curves Form (101, 117) on the phase protection
and Form (102, 165), which is utilized for ground prevention. Normally, a phase
curve applies to Form-116; however, it is unavailable for this work because of an
unacceptable level of adjusting curves. If selected curves are inappropriate, the
recloser may misoperate. The maximum load current of 31 A passes to the recloser,
according to the load flow simulation that is shown on Figure 28. CT ratio sets 1/1 is
responsible for the recloser setting and allows for a program on the control panel and
DigSILENT power factory software. Essentially, the recloser VWVE27 type uses a
CT ratio 1000/1 A, which is applicate in this thesis.
