6.9.5.1.
Excess energy
Up to three channels in each load profile array can be configured as excess energy channels. These are
triggered to record energy quantities once the specified quantity has exceeded a configurable threshold.
These channels can also be configured as
simple
load profile channels.
6.9.6.
Meter billing
The customer is billed for their consumption of energy at regular time intervals called
billing periods
.
6.9.6.1.
Billing periods
A billing period is defined as the time between two successive end of billing (EOB) events. At the end of a billing
period all the energy registers are read and their values recorded as meter data in historical buffer registers.
The utility company then reads this stored meter data and uses it to generate the customer energy-consumption
bills.
6.9.6.2.
End of billing (EOB) event
The meter can be configured so that up to five different sources can trigger an end of billing (EOB) event:
•
generic calendar dates and times (for example, last day of month at 12:00)
•
specific calendar programmed dates (for example, 31st May)
•
an active signal on a control input
•
a command from a communication channel or protocol
•
the front-panel pushbutton reset switch
The meter will always process an EOB event immediately and perform various actions, such as:
•
calculate the cumulative maximum demand value
•
reset the Maximum Demand Indicator (MDI)
•
set the minimum power factor to a value of 1
•
reset various data registers to zero, for example:
•
maxUrms
•
maxIrms
Power failure behaviour
Scheduled EOB events that become due during a period of power failure will be resumed upon meter power-up.
However, only one event is processed at power-up regardless of how many should have occurred during the
power failure period.
