Amps X 1000 Bus3 (Nom. KV 11, Plot Ref. KV 11) : 22EC15 FLA - Other 65 Relay1 Amont - P - 51 OC1

This document contains a one-line diagram showing electrical components on Bus 3 including transformers and protective relays. It summarizes the specifications of two Siemens 7SJ63 relays including their current transformer ratios, inverse time overcurrent settings, and tripping times. It also notes a 0.181 second difference in tripping times between the two relays.
