In today’s global power infrastructure market,   fault alarm systems   must not only react quickly but also present information with absolute clarity. Yet requirements for   alarm color indication   vary widely between countries: 🇹🇭   Thailand:   two-color indication standard   🇯🇴   Jordan:   three-color requirement   🇸🇦   Saudi Arabia:   six-color display for multiple alarm levels Many suppliers struggle to balance these regional differences within one design. ODES sol

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

During protection testing, engineers often need to isolate the protection relay from its connected CT, PT, and control circuits while maintaining circuit integrity and operator safety. The ODES   TSB-14 Testblock , when paired with its test handle, performs three critical tasks in one motion: Controlled isolation  between the relay and external circuits. Automatic CT short-circuiting  to protect the CT secondary. Structured timing  that guarantees “short first, open later.” T
