Overview
The Alpha 4 Residential (A4Res) meter is packed with industry-leading capabilities and processing power for advanced grid applications, delivering real-time data insights and edge intelligence for today’s metering needs.
REVENUE METERINGThe Alpha A4Res meter provides advanced four-quadrant revenue functions, records voltage sag/swell events, and has extensive load profiling and instrument profiling capabilities, all without adding hardware option boards.POWER QUALITY MONITORINGBy sharing a common platform with the Alpha A4CI meter, Honeywell is able to bring PQM to every residential endpoint. Power Quality Monitoring (PQM) provides continuous service condition monitoring 24 hours a day, including open neutral alerts for form 2S services. PQM looks for exceptions to user-defined thresholds for items such as voltage, current, and total harmonic distortion. Each of the 23 PQM tests, run every 200 milliseconds, can be configured to show LCD warnings, record date/time stamp log entries, and send push notifications to a NIC to report the condition. PQM tests do not interfere with any meter functions related to energy ment, and the tests run separately from the metering and instrumentation functions.A COMMUNICATION PLATFORMData can be retrieved using the standard optical communications port. Additional Honeywell communications interfaces are available for A4Res meters as a simple add-on option board. The A4Res also supports push notifications.ENHANCED SECURITYThe Alpha 4 offers all the safety features you come to expect in the Alpha family of meters: magnetic tamper detection, motion detection, and secure 128-bit encryption using ANSI C12.22 communication (even on the optical port). In addition to its extensive event and history logs (1000 entries each), the Alpha 4 meter has the legally relevant parameters (LRP) log beginning with metrology version 3.0. Metercat helps document the features of the LRP log as well as what constitutes a legally relevant parameter.”INTERVAL DATA RECORDING AND SELF READSThe A4Res is packed with 8 MB of nonvolatile memory for storing extensive profile, data logs, self read data and midnight snap shots. Recording options include interval profiles of instrumentation data and up to 40 self reads. The A4Res also stores up to 366 midnight snapshots of the present register data.INSTRUMENTATION PROFILINGWhen instrumentation profiling is enabled, the A4Res meter is capable of recording up to 12 channels of instrumentation data. With instrumentation profiling, each meter becomes a powerful data collection tool to monitor and diagnose problems without installing expensive temporary monitoring equipment. Instrumentation profiling is stored in 1-minute intervals, and the A4Res records up to 79,200 intervals (55 days). The meter can aggregate the data back to the head-end system. One of over 50 instrumentation quantities can be assigned to each channel, and the storage algorithm for each channel can be independently selected. For storage algorithms, most quantities support the following options:• Minimum value per interval
• Maximum value per interval
• Average value per interval
• End of interval snapshot
• Maximum value per interval
• Average value per interval
• End of interval snapshot
