4.5.2  Electricity Measurements 

The principle voltage and the power factor were measured instantaneously and those values 

were assumed to be constant. The phase current used in the calculations was the mean value 

for the measured period. The equipment power loads calculated during operation was based 

on the electricity consumption for the equipment during one batch. This batch was assumed to 

be a standard batch. Each batch has individual holding time and weight, which both affects 

the electricity consumption.
