摘要： A demand electronic electricity meter having load profile recording capabilities is presented. Load profile recording requires memory for storing the recorded information, whereby either on-board memory or external memory is required. Load profile parameters include the number of channels (e.g., 1, 2 or more channels), interval size (e.g., 1, 5, 10, 15, 30 or 60 minutes), quantities to be recorded (e.g., kWh and kvarh, kVAh, or Qh) and channel scalar/divisor (e.g., for each channel, a 2 byte divisor and a 2 byte scalar). With two channels, only two quantities are available for recording, kWh and the one other quantity that the meter has been configured to record, (e.g., kvarh, KVAh, or kQh). For each quantity selected, snapshots of the corresponding total accumulator; (i.e. total kWh and total kvarh, kVAh or kQh) are automatically maintained.

摘要： An apparatus for disposing a meter register in a default mode of operation includes a microcontroller coupled to a programmable non-volatile memory for automatically disposing the meter register in a self-programmed state when the electrical meter containing the meter register is installed for the first time. The self-programmed state is a functional default state and provides a monitoring utility company with accurate customer billing information from the time of installation. Accordingly, a technician responsible for installing the meter in the field need not be familiar with the techniques for programming the meter. If a mode of operation other than the default mode of operation is preferred, the microcontroller can be accessed for disposing the meter in a time-of-use and demand mode of operation or a demand only mode of operation. The microcontroller also provides means for retaining a programmed state of the meter register in the event of a power outage. Thus, when power is again supplied to the meter after an outage, the meter register is again disposed in the last programmed state prior to power failure.
摘要翻译：用于以默认操作模式配置仪表寄存器的装置包括耦合到可编程非易失性存储器的微控制器，用于在第一次安装包含仪表寄存器的电表时自动将仪表寄存器布置在自编程状态。自编程状态是功能默认状态，并且在安装时为监控公用事业公司提供准确的客户计费信息。因此，负责在现场安装仪表的技术人员不需要熟悉用于对仪表进行编程的技术。如果除默认操作模式之外的操作模式是优选的，则可以访问微控制器以将计量表置于使用时间和需求操作模式或仅需操作模式中。在断电的情况下，微控制器还提供用于保持仪表寄存器的编程状态的装置。因此，当断电后再次向仪表供电时，仪表寄存器在断电前再次处于最后的编程状态。

摘要： A programmable multi-channel load profile recorder includes a plurality of memory-based tables, such as a load profile configuration table, a plurality of channel and display configuration tables and an operations table, which can be updated when the recorder is reprogrammed in the field to record additional channels of metering quantities or reconfigured with new formulas. The load profile configuration table containing entries therein for each of a plurality of user-selected metering quantities to be recorded. The plurality of channel and display configuration tables contain parameter data and the operations table contains pointers therein to respective memory-based operation modules, each of which contains executable instructions therein. The metering quantities can be quantities such as watt-hours (Wh), var-hours (Vh), volt-ampere-hours (VAh), volt.sup.2 -hours (V.sup.2 h), ampere.sup.2 -hours (A.sup.2 h) and power factor (PF) as well as other user-selected quantities. According to a preferred aspect of the present invention, each of the tables and modules can be readily updated based on externally supplied data at the time the recorder is programmed. Thus, the recorder need not contain built-in data for determining all the possible channel combinations which might be selected by a user, or fixed formulas for determining all possible metering quantities. The display configuration tables are also provided in memory so that displayable quantities such as RMS line voltage (V.sub.rms) can be displayed by the recorder, even if such quantity is not one of the above-described metering quantities.
