Legacy 3 – DTSY541

Smart Power Quality and Revenue Meter – Three Phase

The Legacy 3, with its innovative and flexible technology based on DTSY541 platform covers metering needs from basic, energy metering to comprehensive smart metering with advanced functionality to support residential, commercial and industrial energy consumers. In alignment with local standards, the Legacy 3 meets and exceeds IEC requirements and provides a range of AMI communication options with protocols like DLMS/COSEM and IDIS.

Legacy-3 meter is a high function, high accuracy, fully programmable Multi-Tariff solid state smart electricity meter. It is ideal for energy and demand measurements on large commercial, industrial and residential consumers. The Legacy-3 is one of the most advanced metering products on the market today, providing a comprehensive perspective of energy usage for critical energy circuits.

The Legacy-3 smart meters provides best-in-class capabilities for accuracy, typically measured at +/- 0.2%. Utilities and their customers can have confidence in the metered value and measured electricity usage.

Meeting New Market Demands

Legacy meters support the new needs arising from deregulation and competition in the electricity market. These meters allow multiple recording of load profiles together with local and remote communication on several lines, and their feature set can be upgraded whenever necessary.

The Legacy smart meters support modular, field replaceable communications to facilitate wide area network communications. Designed specifically to accommodate the varying types of Smart Grid communications technology, the Legacy communications interface supports a broad range of communications options including GPRS, 4G, PLC, RF Mesh and Ethernet.

The communications interface port is common between all legacy variants, allowing a single communications module to suit different meter models. Industry-standard serial interfaces are also available to support connectivity to standalone or multi-drop communications solutions. Direct connect Legacy meters also support built-in power line connectivity to facilitate options such as PLC, DLC, Home Plug technologies.

Success of an AMI system would depend on the introduction and deployment of not only the metering infrastructure and communication technologies to capture and monitor power consumption data, but also the integration with existing operational and enterprise systems so that outage, billing, meter management and business functions of an electric utility could make use of large volumes of more descriptive data being captured and processed in 30 minute rather than one month intervals.

The Legacy 3 meters can be integrated with a variety of smart Grid equipment. Our Meter Data Management solution Cube ESEP10 is a suite of software applications and technology that serves as a robust springboard to optimize utility operational systems outside of traditional billing, such as, coordinated load control, load shedding and load deferral.
