Consider the following power distribution system, equipped with over current relays fuse. Find the current and time setting Relay D ONLY. Assumptions: -The fault clearing time for fuse is the 0.15 to 0.20 seconds. -Coordination time between the relays is 0.3 seconds. -Minimum TMS-0.05. -Overload Factor (OLF) for pickup setting-120% of nominal current for Relays A, B and -Pickup setting interval for relay Dis 20% - For Relay D setting, consider fuse-relay coordination rules. -Standard inverse curve for relays. 1 110415 E 1 MVA 3111 10 MVA ZNY D 1500 MVAC B C 300 15 A 1.10 2007523010016 0.80 10 A 400 15 00 There 1325 80 165 A 3711 10 MVA Fig. 1.
