Question

Q8) Show that a short section of a shorted transmission line appears as if it's an inducto

Answer 1

Short Transmission line Transmission lines having length lesser than 80 km and operating voltage lower than 20kv fall in the short transmission line In a short transmission line the shunt conductance and shunt capacitance are neglected and so only the series resistance and inductance reactance are to be considered. The equivalent circuit is shown in fig (a) where R and x represent the total resistance and inductance reactance of both the consider of a single phase transmission line. Since the effort of shunt capacitance is neglected, series resistance and reactance are taken as lumped. Thus the equivalent circuit of a short transmission is lumped form of (Resistance & Inductor) A simple AC series circuit in calculation the resistance is very negligible, Therefore The short transmission is in General considered as Lumped Inductor
