Consider the transmission link of Problem 2.2 and choose 100 kVA and 2300 V as base kVA and voltage. Determine the input power in per unit under the conditions of Problem 2.2.
Problem 2.2
A three-phase transmission link is rated 100 kVA at 2300 V. When operating at rated load, the total resistive and reactive voltage drops in the link are, respectively, 2.4 and 3.6 % of the rated voltage. Determine the input power and power factor when the link delivers 60 kW at 0.8 PF lagging at 2300 V.
