Procedure for calculating the power (KVA) requirements of a Generator.
example:
A house has 10 tube lights, 5 Bulbs, 6 Ceiling Fans, 1 TV, 2 Personal Computers, 1 Laser Printer, 1 Iron Box etc.,
* write down watts or Volts and Amps from each equipment
printed on its cover or in the manual.
1 Tube Light = 40 watts, 10 Tube Lights = 10 X 40=400Watts
1 Bulb = 60 watts, 5 Bulbs = 5 x 60 = 300 Watts
1 CeilingFan = 80 Watts, 6 C.Fans=6 x 80 =440 Watts
1 TV = 135Watts,
1 Personal Computer=275 Watts, 2 PC = 2 x 275=550Watts
1 Laser Printer = 375 Watts
1 Iron Box= 1000 Watts
* Add all the Wattage
400+ 300+440+135+550+375+1000=3200 Watts
Total Watts = 3200
* By Dividing with 1000 we get Kilo Watts
3200/1000 = 3.2 Kilo Watts or KW
* Take Power Factor is 0.8 ( it depends upon the system
Efficiency)
* By Dividing 3.2 KW by 0.8 we get the Required KVA
3.2 / 0.8 = 4 KVA.
Now select the Generator that is having 4 KVA
Power generating capacity.
