# An overhead line is connected in series with a cable. The overhead line has an inductance of 2mH/km and capacitance of 0.01ûF/km. The cable has an inductance of 0.25H/km and capacitance of 0.102ûF/km. If a surge having a maximum value of 100kv travels along the overhead line towards its junction with the cable. Calculate

C) Derive from first(1st) principle, the load flow equation

B) An overhead line is connected in series with a cable. The overhead line has an inductance of 2mH/km and capacitance of 0.01ûF/km. The cable has an inductance of 0.25H/km and capacitance of 0.102ûF/km. If a surge having a maximum value of 100kv travels along the overhead line towards its junction with the cable. Calculate
I) The velocity of wave propagation in the line and cable
II) The surge impedance of line and cable

On the 4th of November I officially became a member of the exclusive 1st student with distinction after five years of no such record, in the history of The Polytechnic Ibadan, Faculty of Engineering to graduate with distinction as a DPP students since its establishment in 2011. My unrelenting power to solve problems, have made me to create a platform where student can get valid information anywhere, anyplace at anytime Evolving education world wide 🌎
