The setting value is set based on vendor relay curve characteristic and the characteristic of protected load or equipment. The protected loads can be a single motor, transformer, another downstream equipment panel and lighting. But for this study the protected load at the downstream stated as Lump Load for simplified study. In order to coordinate well between upstream relay and downstream relay, upstream relay will follows on biggest load relay setting and general accumulative characteristic of all loads, Which are covered by the upstream relay. Coordination between upstream and downstream sketch on attachment 01 - For Transformer protection, 98.7% of FLA (190 A) is recommendable as overcurrent tap setting. - Inrush current transformer is 800% of FLA (1540 A) at 0.45 seconds. = CT rating is 20/5 - Relay on 6KV switchgear in this ETAP simulation used GE Multilin MDP - Starting load simulation is Chiller Unit 95 kW; 157,6 A STUDY CASE Calculation Normal operation condition, all normal loads are supplied from Line 2; Bus 3; VCB 9. a.
