Chapter 11 Multi-tariff feature
This section describes how to set up different tariffs for storing energy values in
registers that correspond to each of those tariffs. An example of when this feature can
be used is when a utility has set up tariff schedules with different rates based on what
day or time of day energy is consumed.
The meter supports configuration of up to 8 different tariffs.
Multi-tariff feature example
In the above illustration, the area under the power curve equals the energy consumed.
Typically, the utility sets tariff schedules so the cost of energy is higher during high
demand or high energy consumption times. How these “tariff energy containers” are
configured determines how fast these containers fill, which correlates to increasing
energy costs. The price per kWh is lowest at tariff T1 and highest at tariff T2.
Multi-tariff feature overview
The meter supports multiple tariffs to measure and monitor energy usage that can be
used in billing or cost applications. There are different tariff modes you can use to
determine what tariff is applied and when: Command mode, Time of Day mode, and
Input mode.
