Smart electricity meter - Industrial

As power systems have become increasingly decentralized and interconnected, utilities, industrial facilities, and critical infrastructure operators require greater visibility into energy flows and network performance. Smart electricity meters have evolved beyond traditional energy measurement to become intelligent endpoints within modern grid architecture. By combining revenue-grade metering accuracy with secure communications and remote data acquisition, smart meters deliver actionable insights that support operational optimization, demand-side management, outage detection, and distributed energy resource integration. Their ability to provide granular, near real-time data makes them a foundational element of resilient, efficient, and digitally connected Smart Grid networks.

Design considerations

  • Three-phase revenue-grade metering requires highly accurate current and voltage measurement across a wide operating range.
  • Robust power conversion is needed to efficiently derive low-voltage rails from the mains supply while meeting safety and regulatory requirements.
  • Backup power capability ensures critical functions such as event logging, relay control and last-gasp communication remain available during outages.
  • Galvanic isolation and protection are essential to safeguard low-voltage electronics, communication interfaces and users from hazardous voltages and transient events.
  • Secure wired and wireless connectivity enables remote meter reading, diagnostics,  firmware updates and integration into Advanced Metering Infrastructure (AMI) networks.
  • Reliable data acquisition and processing support energy monitoring, load profiling, power quality analysis and distributed energy resource integration.
