7. ENERGY COST PER YEAR (EB) 3.35 X 12 HOURS X 30 DAYS= 1206 kwh 1206 x 5.5 = Rs.6633/- per month Rs.79596/- per year

8. EXPENDITURE ON EA SET COST OF FUEL : Rs.35/ LTR RUNNING HOURS : 12 HOUR/DAY CONSUMPTION: 1.6 LTR /HOUR EXPENDITURE PER MONTH: 1.6 X12 X 35 X 30 = Rs.20160 EXPENDITURE = 2,41,920/- PER YEAR

9. COST OF PHASE SELECTOR SWITCH AND INSTALLATION CHARGE = Rs. 12,000/- EXPENDITURE ON EA SET

10. 12 HOURS WORKING PER DAY FUEL CHARGES =Rs.2,41,920/- EB CHARGES = RS. 79596/- SAVING PER YEAR = Rs.241920 –( 79596+12000/-) =Rs.1,60,324/- FUEL SAVING : RS.1,60,324/- PER YEAR. EXPENDITURE ON EA SET

11. RECOMMENDATIONS SINGLE PHASE POWER PLANT WITH PHASE CHANGER IS ECONOMICAL WHERE DISRUPTION OF ONE PHASE BY EB IN PRACTICESINGLE PHASE POWER PLANT WITH PHASE CHANGER IS ECONOMICAL WHERE DISRUPTION OF ONE PHASE BY EB IN PRACTICE EB METER CAPACITY SHALL BE 20AMPS PER PHASEEB METER CAPACITY SHALL BE 20AMPS PER PHASE COST OF PHASE SELECTOR SWITCH CAN BE RETRIEVED WITHIN ONE MONTHCOST OF PHASE SELECTOR SWITCH CAN BE RETRIEVED WITHIN ONE MONTH

12. RECOMMENDATIONS THREE PHASE POWER PLANT IS ECONOMICAL IN URBAN AREAS WHERE CONTINUOUS 3PHASE POWER SUPPLY IS AVAILABLE.
