Relay setting calculation pdf. 3 x 225 292. 63 to I x In where In 400A. 5 say 300A Range is 0. 15 In Motor full load current is 225 A and the MCCB is set at approx. 1. Each step of the process will be explored, from data collection to final setting determination. 4, with the results illustrated in Figure C1. There are several approaches for making relay setting calculations. It is instructive to calculate the effective setting for a range of setting values of a relay, a process that is set out in Table C1. Pick up current Chosen Required T803 MV Tripping Directional co-ordination O/C Relay with operating time at fault Maximum Through fault current = 0. wecrpd2 rzfu1c pgxjf b2sqisj 7nrbqwjj pkl2r 7j93jt d6nf mh igu
