Intermediate relays rarely take center stage in substation design, yet they directly determine wiring quality, maintainability, EMC robustness, and long-term reliability in both primary and secondary circuits. For a complete overview of ODES relay and control products, visit www.odes-electric.com . Leveraging its protection-relay engineering background, ODES developed three plug-in relay families to cover the full range of substation and industrial applications: RT

When accidents occur in a substation, the control power—not the primary circuit—often decides whether the system “can still see, can still act.” If a single link in the control-power chain fails, protection IEDs, merging units, gateways, clocks, and communication devices may all go dark. That is why dual-source control power with reliable automatic switching is not an optional enhancement—it is a requirement for modern protection and station-control systems. Learn

Dual DC Control Power as a Non-Negotiable Baseline In 220 kV and above substations and power plants, it is now standard practice to provide two fully independent DC systems for protection, measurement and control, communication, and bay controllers. Yet in many projects, the weakest link is not the station battery itself, but the way A/B DC is distributed and switched at the panel level. A single DC disturbance or maintenance outage on one section must never drop a protection
