- A One-line diagram of a part of a three-phase power system is given below: The equipment ratings are as follows: G line LOAD ΔΥ G: 75 MVA, 13 kV, X= 0.12 p.u. T: Three-phase bank of three single-phase transformers each rated 30 MVA, 132.7905 kV /11 kV with X= 0.15 p.. Line: X= 400 Ohms Load: Wye connected with 900 +j360 Ohms in each phase. Using Share 100 MVA and Mossel 11 kV for the generator side of the system, determine per unit impedances of all the components and draw the impedance diagram of the given system.
