Electricity meter | Alfa A1700 | Russia

The ALFA A1700 three-phase, multi-tariff, electronic electric meter is a development of the Elster concern in the field of electricity metering and the organization of ASUE. The scope of the ALFA A1700 meter is a complete and accurate commercial and technical accounting in the large industrial and small-engine sector.

For the first time, the ALPHA A1700 counter uses a modular design and interface independence. The A1700 meter can additionally take into account the consumption of various types of resources and energy received via telemetry channels from other meters (water, heat, gas). Thanks to this, as well as a wide range of functions of the ALFA A1700 counters, absolutely new opportunities for accounting and organization of ASUE systems appear.

features:
Microprocessor multifunctional electricity meters ALFA A1700 are designed to account for active and reactive energy in three-phase alternating current circuits of transformer switching, in single- and multi-tariff modes with accuracy class 1.0, while the number of tariff zones can reach 16. The ALPHA A1700 meter operates in a wide range of operating currents and voltages, has high sensitivity. The ALPHA A1700 meter measures and displays the parameters of the electrical network - voltages and phase currents, active, reactive and full power of the three-phase system, as well as service data.

The developed modern AlphaPlus 100 software allows not only to read data from counters via an optical port and a digital interface, but also to completely reprogram the counter. The latest version of the software can be downloaded in the corresponding section of the site.
Completely new features are provided by the A1700 counter for the organization of ASKUE. Pulse inputs/outputs and digital interfaces and even a built-in GSM modem can be used independently to communicate with the A1700 meter. An interesting feature of the ALPHA A1700 is that additional interfaces are connected without disconnecting the meter and violating metrological seals.

All measured and calculated data, including those received from other counters via pulse channels, the ALPHA A1700 counter stores in non-volatile memory. The capabilities of the ALPHA A1700 counter allow you to store load graphs on 16 channels, while the storage period of graphs can reach 900 days. The ALPHA A1700 meters use the technology embedded in the ALPHA series meters, which has long proven its high accuracy and reliability.

The ALPHA A1700 meter provides:
A wide range of multi-tariff functions for electricity accounting.
The ability to perform measurements in multi-tariff mode and display them on the LCD.
The ability to store load graphs on 16 channels.
The number of channels of load graphs, the duration of the averaging interval, the measured parameters by which load graphs will be accumulated are set programmatically.
Reliability of information on electricity metering due to self-diagnosis functions and protection against unauthorized access to commercial information.
Reading all the necessary data to a laptop computer via an optical port (IEC 1107 standard).
Using independent pulse outputs and RS-232 and RS-485 digital interfaces, as well as a built-in GSM modem for the operation of the meter in the ASKUE.

Multi - tariff:
Up to 16 tariff zones for energy metering.
Up to 8 tariff zones for capacity accounting. The schedule of tariff zones is compiled taking into account 12 seasons.
Tariff zones for power may differ from tariff zones for energy. The schedule of tariff zones can be repeated many times and compiled taking into account the twelve seasons. The schedule and the tariff zones and seasons themselves can be reprogrammed using the AlpaPlus100 software.

Deferred tariff:
In the meter, you can program a second schedule of tariff zones (deferred tariff), which will take effect from a predetermined date, instead of the current schedule.

In the deferred tariff, it is possible to set other parameters:
Dates of the change of seasons;
Schedules of tariff zones for energy and capacity;
Special dates;
Sets of parameters to display on the LCD.
The parameters of the deferred tariff and its effective date are set programmatically.
