Voltage phasors at the end of a 3phase transmission line are

Voltage phasors at the end of a 3-phase transmission line are given:

Draw the phasor diagram showing both voltages and the line current, and determine, and clearly explain your answer: The direction of flow of the active power, P: The Sending-End power factor, pf:

Solution

as Bus M has source voltage magnitude more than the Bus N, therefore Bus M acts as source and power flows from the Bus M to Bus N,

and power factor of source is legging
