If voltage and current phasors at one end of a branch are known, then voltage phasor at the other end of that branch can be obtained. These are called pseudo measurements.

In this model, alternating voltage and the corresponding current can be represented with counterclockwise rotating arrows called phasors. Following is the phasor diagram for AC current. Using the same strategy as described for current, draw the phasor diagram representing AC voltage.

By how many degrees? The current leads the voltage by 90(. Since the phasors rotate counterclockwise, the voltage phasor for the capacitor must lie 90( clockwise from the current phasor. Now consider the voltage phasor for the inductor. It is critically important to remember the phase relationship between the current and voltage for an inductor.

The voltage-current relationship is, . In phasors, it is clear that, , and that voltage and current are “in phase” and the ratio = R Ω. For an . inductor,, so if , then. Thus, the voltage “leads” the current by 90° (or restated, the current “lags” the voltage by 90°).

V2 and I2 (the voltage and current phasors on receiving end of the transmission line) y and z and therefore γ and ZC. And from this, we compute V1 and I1 (the voltage and current phasors on sending end of the transmission line) using eqs. (1), (2). Note it requires evaluation of the hyperbolic functions. We illustrate details of this. With
