4. A factory takes a load of 800 kW at 0-8 p.f. (lagging) for 3000 hours per annum and buys energy on tariff of Rs 100 per kVA plus 10 paise per kWh. If the power factor is improved to 0-9 lagging by means of capacitors costing Rs 60 per kVAR and having a power loss of 100 W per kVA, calculate the annual saving effected by their use. Allow 10% per annum for interest and depreciation on the capacitors.

Problem : In the case of an industrial load with a power factor of 0.707 lagging, consuming 100 kW, and the line voltage at 60 Hz is 480Vrms, with a line resistance of 0.1Ω between the power company's transformer and the load, calculate the amount of power saved if the load's power factor changes to 0.94 leading. The answer is "3.771 Kilo-Watt has been saved" and also I want to know the concept of 'Power Factor'.
An industrial assembly hall is continuously lightedby one hundred 40-W mercury vapor lamps suppliedby a 120-V and 60-Hz source with a power factor of0.65. Due to the low power factor, a 25 percent penaltyis applied at billing. If the average price of 1 kWh is$0.01 and the capacitor’s average price is $50 permillifarad, compute after how many days of operationthe penalty billing covers the price of the power factorcorrection capacitor. (To avoid penalty, the powerfactor must be greater than 0.85.)
