".I need the correct answers with explanations" A power station has a daily load cycle as under: 260 kwh for 6 hours; 200 kwh for 8 hours: 160 kwh for 4 hours, 100 kwh for 6 hours. If the power station is equipped with 4 units of 75 kw each, calculate (i) daily load factor (ii) plant capacity factor and (iii) daily requirement of fuel in kg if the calorific value of fuel used were 10,000 kcal/kg.

"I need the correct answers with explanations" Pick up the correct answer 1. The area under the daily load curve gives A. average load in kw B. units generated in kwh 2. the minimum phase-neutral voltage at which corona A. Visual critical voltage B. Receiving voltage C. plant capacity in kw D. Maximum demand in kw occurs is C. String voltage D. Critical disruptive voltage. 3. If the length of a transmission line increases, its inductance is B.
