1.22.- Billing closures
A billing closure is considered to mean the storage, in a memory register and at a determined
moment, of the following values:
Values indicated by the energy totalizers at a given moment (absolute reading).
Values of the energy measurements since the previous closure or since the start-up
of the meter, in this closure is the first (incremental reading).
The measurements and calculations that must be stored are:
Active energy, as both absolute and incremental values.
Inductive and capacitive reactive energy, as both absolute and incremental values.
Calculated average maximum active power in a quarter of an hour.
Calculated power excesses.
The billing closures are over the total measurements and all the tariff periods of the active
contracts.
Each closure includes the associated date and time when it took place. A minimum,
configuration, time must elapse between two consecutive closures, expressed in minutes. By
default, this time is 10 minutes.
The meter keeps a historic register of the 12 most recent closures for each of the contracts
that it holds, arranged chronologically from the most recent to the oldest.
The types of closure are:
This closure can be made at any time by means of a manual order, by pressing a
button or sending a communications message. The power values are considered up
until the end of the quarter-of-an-hour integration period immediately prior to the
moment in which the order is given. The energy values will be those indicated by the
totalizers in the moment the order is received. Ordering a closure manually using the
button affects all of the active contracts. A closure via a communications message
may affect one or more of the active contracts.
Automatic closure. Programmable parameters indicate the date on which each
contract is to be closed automatically. The date can contain wildcards in the month
and year. This type of closure can affect one or more of the active contracts
An extraordinary immediate closure is automatically carried out in the following cases:
Change of transformer ratio. This affects all contracts.
Change of contracted power per period. This affects the modified contract.
Change of season or type of day. This affects the modified contract.
