Substation Automation Systems for Power Grid Control
Elseta is a forward‑looking European company and trusted partner in substation automation, offering compact, field-ready RTUs, I/O modules, and measurement devices tailored for utilities, distribution network operators, and OEMs. Our innovative solutions bring local intelligence to the edge—real‑time monitoring, on‑device logic, and secure remote access—without the need for bulky infrastructure or proprietary stack limitations.
Our Mission & Values
Elseta is a European company based in Lithuania, founded on the belief that electrical energy is the backbone of tomorrow’s society. Our mission is to create smart, modular devices—like RTUs, I/O modules and fault detection modules—to deliver electrical substation automation that empowers utilities, renewables and industrial automators.
We answer what is substation automation with precision and scalability. In today’s competitive market for energy and grid infrastructure, Elseta’s modular products stand out. We enable grid operators to modernize their electrical system with secure, scalable automation in substations. Our tools simplify deployment, commissioning, and long‑term evolution of field equipment.
Products
Our RTUs support communication protocols like IEC 61850, Modbus, IEC 60870-5-101/103/104, DNP3, Modbus, DLMS, Mbus, etc., to ensure interoperability with any grid or SCADA.
This equipment forms the backbone of modern grid communications for automated control in digital substation automation systems.
WCC Lite
Mini RTU designed for rapid deployment in secondary substations, switchgears (ring main units), reclosers, etc.
eRTU
Next‑generation Feeder Remote Terminal Unit with integrated HMI, built‑in power supply management, and fault indication.
IOMod
I/O modules, sensors, current & voltage adapters, fault passage indicator (FPI) units and other accesories
Use Cases
Elseta empowers modern grid systems with intelligent automation in substation operations, placing adaptive control and diagnostics right at the electric edge. By embedding real-time logic, monitoring, and secure connectivity into field devices, Elseta enables smarter responses across substations. This results in enhanced operational resilience, optimized electricity distribution, and stronger network coordination—uplifting grid uptime and reducing intervention cycles.
Substations
For utilities and distribution network operators, Elseta offers RTUs, I/O modules, measurement modules, and FPI units that directly enhance feeder reliability and load management. These tools enable automated feeder control, fault detection, and remote monitoring across secondary substations and switchgears. The architecture allows field-level data and logic to execute where it’s needed, reducing response times and minimizing human intervention. Operators gain stronger power stability through SCADA-integrated dashboards, enabling live visibility of events and substation devices. The result is fewer service interruptions and increased network resilience.
Renewables
Elseta supports renewable energy producers and microgrid operators with solutions crafted to integrate distributed resources into the electric grid of the distribution network operators effectively. From solar farms and wind parks to hybrid energy storage, our devices provide real-time data logging, reactive power support, frequency control, and steady performance under variable load conditions. These solutions help align generation with demand, improve energy quality, and support remote maintenance. Integration into SCADA and grid-level management ensures DER sites are not islands but active, responsive parts of a modern, automated infrastructure.
RMU Automation
Ring Main Unit (RMU) automation is a critical piece of modern power distribution. Elseta’s RMU automation solutions include compact controllers, such as the WCC Lite and eRTU, that control switchgear, provide status and position indication, integrate fault passage indicators, protection relays and other RMU inteligent electronic devices, and communicate with control centers. They allow RMUs to act not just as passive switchgear but as intelligent nodes: performing open/close operations remotely, isolating faults, restoring power paths, and switching loads automatically. With RMU automation, downtime is reduced, operations are safer, and remote sites can be managed with minimal intervention.
Protocol Conversion
Elseta enables legacy and multi-vendor environments to communicate smoothly via protocol conversion. Many substations still use older or mixed communication protocols. Our WCC Lite or CMU modules can act as protocol conversion modules that translate between Modbus, IEC 60870-5, DNP3, IEC 61850, and other protocols, allowing modern RTUs and SCADA systems to interoperate without expensive rewiring or full system overhauls. This ensures that new Elseta equipment can plug into your existing infrastructure, extending its life and avoiding vendor lock-in, while enabling future scalability. Because of its size, the WCC Lite most likely will fit anywhere where it is needed.
