Elseta is proud to unveil its newest innovation in grid automation: eRTU, a next-generation remote terminal unit designed to bring advanced control, measurement, and automation capabilities to modern power distribution networks.
As utilities and system integrators face growing demands for reliability, real-time monitoring, and responsive automation at the edge, the eRTU delivers a powerful new platform built from the ground up for today’s smart grid challenges.
At the heart of the eRTU is a modular architecture combining a high-performance Communications & Measurement Unit (CMU) with expandable bay control modules (BCM1P). This enables secure remote control, high-precision data acquisition, and self-healing network logic in one compact, rugged design — ideal for feeder automation, secondary substation control, and RMU-based schemes.
The eRTU offers a suite of advanced features, including:
- Comprehensive fault management with bidirectional detection and automatic isolation, enabling faster restoration and enhanced grid resilience.
- High-precision power quality analysis, delivering detailed metrics and disturbance records for deeper operational insight.
- Flexible communication options, from cellular (including optional 5G) to fibre or legacy protocols, with redundant communication paths.
- Cybersecurity by design, with multi-layer security, encrypted communications, and IEC 62351 compliance.
- Scalable platform architecture, allowing easy growth from basic monitoring to complete feeder automation.
With its compact footprint and rugged build, eRTU is ready for deployment in demanding environments — from medium-voltage distribution feeders and renewable energy sites to critical industrial micro-grids.
“This next generation of RTU reflects Elseta’s commitment to innovation and future-ready grid automation,” said the Elseta product team. “The eRTU equips utilities and system partners with the performance, flexibility, and security needed to meet evolving grid needs.”
The eRTU expands Elseta’s product portfolio alongside established solutions like the WCC Lite mini RTU, bringing a powerful automation option to integrators, utility operators, and OEMs alike.
