Elster Alpha Plus Meter Technical Manual

Posted By admin On 04.01.21

The ALPHA Plus® meter is a totally electronic single phase or polyphase electricity meter and integral register that collects, processes, and stores energy use and demand data on either a single rate or time of use (TOU) basis. It meets or exceeds the American National Standards Institute (ANSI) standards for electricity metering and is certified for use by industrial and electric utility customers. It has been certified for direct access use in California.
ALPHA Plus is the first meter in its class that can time/date/phase stamp voltage sags as short as 2 line cycles in duration. An internal log maintains this information for the last 40 sags.
ALPHA Plus meters support metering requirements ranging from kWh and kW demand meter to multi-rate, real/reactive meter that automatically validates service connections, provides instrumentation readings and load profile readings with remote communications. ALPHA Plus meters are available in a variety of configurations to meet your revenue metering requirements. The meters also offer a PQM (power quality monitoring) option. This feature helps isolate the cause of transients, harmonics and sags. PQM monitors circuit parameters on a cyclic, 24-hour basis throughout the billing period and recognizes deviations beyond the programmed threshold for each phase.
Instrumentation on the ALPHA Plus meter are display quantities that assists in evaluating the service by providing real time analysis of the conditions present at the meter installation. The instrumentation measurements are near instantaneous and require no memory storage within the meter. Using Elster meter support software, system instrumentation may be configured to select which quantities to display as well as the display sequence where they will be shown.

The ALPHA Plus Meter Technical Manualcan be referred to by its document number: TM42–2182. Each revision of this manual is designated with a letter, with the first revision being “A,” the second being “B,” and so forth. The document number and revision letter are located at the bottom of each page.
Building on patented ALPHA meter technology, the A3 ALPHA meter is the first Elster Electricity meter to support the American National Standards Institute (ANSI) C12.18, C12.19, and C12.21 standards. The A3 ALPHA meter provides a meter design platform that supports a variety of metering requirements.
AlphaPlus™ is a comprehensive software interface for configuring meter functions including: programming and reading, report generation, and program development and maintenance. AlphaPlus software was developed for use with demand, time-of-use (TOU), load profile, and real/reactive meters, including the ALPHA Plus® and AIN ALPHA® meters.
