The system shown in Fig 23 of a transmission system and the positive and zero sequence impedances for the various elements are given in the figure. In addition, the following information are given: The CT ratio is 600/5 and the VT ratio is 1000/1 The power transfer from Pance to Juanchito is 30.4MW and 13.2MVAR (5 marks): Determine the three zone settings (Zone 1 to 3) for the distance relay installed at the Pance Substation (at Bus 10) considering no current infeed effect. b. (3 marks) : Check if whether the maximum load will encroach into zone 3 mho characteristic? C. (1 marks): If a directional impedance characteristic is used, what will be the appropriate setting for the directional unit?
