7.10.2. Total energy registers (TER)
Total energy registers (TER) are:
dedicated to storing the total accumulation of an energy quantity
independent of any tariff switching or calendar definition
not reset at the end of a billing period
not programmable
Total energy registers can be configured to accumulate energy in three discrete multiplier steps, as shown in the
watt hour (Wh) example below (kvarh and kVAh follow the same pattern):
Unit Value Name
Wh Watt hour
kWh 10
3
Kilowatt hour
MWh 10
6
Megawatt hour
Note: It is very important that the register multiplier is chosen correctly with regard to the meter installation
requirements and summation register values.
Energy register contents are displayed with a maximum of eight digits, the following table illustrates the full range
available for each unit multiplier:
Unit Energy register unit Energy register max value
Wh 99 999 999 Wh 99 999.999 kWh
kWh 99 999 999 kWh 99 999.999 MWh
MWh 99 999 999 MWh 99 999.999 GWh
The maximum energy register value is just under 100TWh.
7.10.3. Energy registering
All the measured energy quantities (page 33) recorded by the meter are available for energy registering, such as:
Per phase
Aggregate
Summation
7.10.3.1. Energy channels
For energy registering purposes the meter can be configured with up to ten independent energy channels, each
channel being selected from the available measured energy quantities. If required, a specific energy quantity can
be allocated to more than one channel and three channels are available for excess energy accumulation.
Typically, only energy channels configured with active and reactive energy types are used for billing purposes.
However, it is possible to configure any remaining channels with alternative energy quantities for analysis
purposes.
