Two overhead lines AB (Z0 = 500 Ω, length = 300 km, attenuation factor = 0.8) and BC (Z0 = 300 Ω, length = 120 km, attenuation factor = 0.9) feed a load of surge impedance 1700 Ω at C. A triangular wave of peak height (875)/2 kV and duration 300 µs originates in the overhead line AB at A and travels towards B. Using Bewley Lattice Diagram, determine and sketch the voltages at A, B and C for the first 2 ms. A to J z0=500 ohm, C to J z0 = 300 ohm B to J z0 = 400 ohm D to J z0 = 50 ohm.
