Answer:
The receiving end Voltage ( VR ) will reduce significantly
Explanation:
Determine what happens to the receiving end voltage
Given that ; Load on transmission line is increased and Load has a lagging power factor
Increase in load = Increase in reactive/real power drawn from the transmission line and this will cause an increase in the current drawn as well.
Vs = VR + j XL I
Vs = sending end voltage
VR = receiving end voltage
jXL I = voltage drop across reactance
The rotating and shifting of Vs to a new power angle ( lagging power factor ) without a change in magnitude will cause the value of the VR receiving end voltage to drop significantly
