A meter has a constant of 600 revolutions per kWh. If the meter makes 10 revolutions in 20 seconds, what is the load in kW?
Right Answer is:
Meter constant K = Number of revolution/Kwh (rev/kWh)
Number of revolution = 10
Energy consumed when the disc made 10 revolution
= 10 × 1/600 = 1/60 KWh
Now energy consumed is equal to load in kW multiplied by time in hours i.e.
Load × 20/3600 = 1/60
Load = 3600/120
Load = 3 kW
