Hi all!
I was asked to calculate KWh values for all the motors within our plant. I figured I'd go about calculating the values by gathering the data on each motor then multiplying the Volts x Amps to get the KVA of each motor. Once I had the KVA for each motor, I was going to then multiply it by the power factor of the motor to get the total KW consumption of the motor. Once I had the KW for the motors I would then multiply this by the hours (was asked for consumption for a year with a runtime of 92%) to get my total KWH for each motor over the course of a year. Is this the correct way for going about calculating the KWh for each motor over the course of a year.
Does the 92% runtime mean to take 92% of the hours in a year to use as my number of hours for the motor running?
One las question, I cant find a Powr Factor for two of the motors which are .75 h.p. Is there an average or ideal power factor I can use for these motors in my calculations, since I cant find the actual power factors.
Thank you
