Application of the JAYA Algorithm in Solving the Problem of the Optimal Coordination of Overcurrent Relays in Single- and Multi-Loop Distribution Systems

Table 7

Primary/backup relationships and total fault current of the relays.

Fault point	T. fault current	Primary relay	Back relay
A	2330	1, 2, 8	—, —, 3
B	1200	3, 4	—, 1, 2
C	1400	3, 7	—, 4
D	1400	4, 8	1, 2, 3
E	2800	1, 5	—, 8
F	2800	2, 6	—, 8

— Indicates the fault is not seen by the relay.
