ABSTRACT
As stated earlier, the eect of the line capacitance are neglected for a short transmission line. erefore, while studying the performance of such a line, only resistance and inductance are taken into account. e equivalent circuit of a single-phase short transmission line is shown in Figure 9.1a. Here the total line resistance and inductance are shown as concentrated or lumped instead of being distributed. e circuit is simple AC circuit, where I is the load current, R is the loop resistance or resistance of both conductors, XL is the loop reactance, Vr is the receiving-end voltage, cos ϕR is the receiving-end power factor, Vs is the sending-end voltage, and cos ϕS is the sending-end power factor.
