Author: Yunxiang Zhang — Global Liaison, ODES Electric Introduction — Choosing Reliability in the Smart Grid Era The Chinese power‑automation landscape is entering a decisive decade. Substation retrofits, intelligent switchgear, and digital twins are reshaping how engineers protect and monitor the grid. Measuring relays — the nerve endings of automation — must deliver not only precision but also interoperability, cybersecurity readiness, and lifecycle transparency. For engi

The Role of Temperature Transmitters in Protection and Monitoring In modern protection and control systems, accurate temperature measurement is essential to assess transformer health and prevent thermal faults. Parameters such as core temperature , winding temperature , and oil temperature form the foundation of transformer “tri-temperature” monitoring. The STT Series temperature transmitters from ODES are engineered for this purpose. Designed to meet IEEE and
