AYSIA Q2. (a) A radial distribution system with source at one side of the feeders, each with maximum load based on MVA rating is shown Figure Q2. Determine the nominal current at each relay and propose suitable setting (PS) for all relays, considering nearest possible value. (PS: 20% 250% in step of 10%) (6 marks) PRO NIVERSITI TEROL Use PAN UNTUK MANUSIA (b) Based on fault current given at Table Q2. Determine the suitable Time Setting Multiplier (TSM) of all relays to achieve well-coordination system. TSM ranges from 0.01 to 1.0 in step of 0.01. The discrimination time (DT) set at 0.35s. TSM for R1 and R2 are given 0.1. The relay characteristic operating time (RCOT) is given by: 0.14 RCOT = PSM0.02 - 1 (9 marks)
