The measured energy (partial energy) is placed in TARIFF
1 when the time period is from midnight to e.g. 8:00am, in
TARIFF 2 when the time period is from 8:00a.m. to 08:00p.m.
and again in TARIFF1 when the time period is from 08:00p.m.
to midnight. The total measured energy is the result of the
sum of all the partial measures as shown in the figure below:
