4.8.3 Energy costs calculator
a. Functional Description
When the parameters recorded by the recorder include active energy E
P
, it is possible to calculate the
energy costs according to the cost calculator set by the user. To enter the screen of the energy cost
calculator, use the bar on the recording summary window (section 4.7 step ) and select icon .
The screen with energy costs will be displayed as shown in Fig. 4.25. The following sections present:
Recording time – start, end and duration of the recording. The last line
shows the duration which is analysed by the algorithm of the cost calculator (full aggre-
gation periods). The algorithm enables the calculation of the energy costs for the whole re-
cording period and there is no option to select a different time interval.
Energy – this field displays the total active energy in kilowatt-hours measured in the reporting
time interval.
Single zone tariff – this section displays the total cost of energy in the selected currency for
single-zone variant. The tariff of this type has a single flat rate per kWh, regardless of the time
of day and day of the week. Tariff type (may be modified by the user) is displayed in the up-
per part.
Multi-zone tariff – shows the total cost of energy in the chosen currency in the multi-zone
variant. This tariff allows you to define two continuous time intervals in 24 hours, which have
different cost rates per kWh, and the third the rate for other times of the day. Tariff type (may
be modified by the user) is displayed in the upper part. Configuration of rates and zones is
carried out in the control panel of the energy cost calculator.
If you have not used or have not changed the settings of the cost calculator, the recorder will use
the default settings. The settings of the cost calculator may be modified by selecting from the menu
bar the icon.
