EVOSYS provides a comprehensive suite of Substation Telecommunications services engineered for the 99.99%+ availability required for Substation infrastructure. We design and deploy the secure, resilient nervous system that enables real-time monitoring, precision control, and ultra-fast protection coordination across the electrical grid.

Teleprotection & Control Messaging

We specialize in low-latency peer-to-peer messaging to replace traditional hardwiring.

  • Mission-critical inter-substation signalling ensuring round-trip optimized latencies for reliable fault clearance.
  • Full-spectrum PLC system design, including primary equipment integration (Line Traps, CCs, CVTs, and LMUs).
  • Mission-critical signalling over C37.94, Fiber, Radio, and legacy Pilot Wire to ensure ultra-fast fault clearance.
  • Ultra-fast protection signals for busbar interlocking and breaker failure schemes.

SCADA Telemetry & Remote Connectivity

Our designs ensure the Control Centre remains connected to the field, no matter the conditions.

  • Design of high-availability SDH/PDH, DWDM/CWDM, and high-capacity Microwave backhaul.
  • High-bandwidth MPLS VPN, leased lines, or private Ethernet utilizing DNP3 or IEC 60870-5-104.
  • Automatic <1s failover to Cellular (4G LTE/5G) or licensed radio, providing geographic and media diversity.
  • Seamless integration of legacy hardware into modern digital twins through multi-protocol conversion (Modbus/serial to IEC 61850).

IP & Digital Automation:

Advanced IP Networking specializing in IEC 61850 station and process bus architectures.

Wireless & Radio

Deployment of Outdoor/Indoor Wi-Fi, Land Mobile Radio (LMR), and robust Ethernet Radio links.

Bespoke Telecom Panel Building

EVOSYS delivers specialized Design, Assembly, and Factory Testing of dedicated Telecom and Network panels, ensuring they meet the harsh environmental and EMC requirements of substation environments:

  • Network & Gateway Suites: Custom-built racks for MPLS routers, SDH/PDH nodes, and protocol gateways, featuring optimized cable management and thermal cooling.
  • Fiber Termination & Patching: High-density Optical Distribution Frames (ODF) and splicing enclosures for robust OSP/ISP fiber management.
  • Teleprotection Panels: Integration of specialized signalling equipment with dedicated auxiliary power monitoring and failover logic.

End-to-End Validation (FAT/SAT)

Every system is validated through rigorous protocol compliance testing, failover drills, and penetration testing. Our handover includes comprehensive As-Built documentation, VLAN maps, and firewall configurations to ensure long-term operational readiness.
