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.
