A standards-compliance update for customers using ODES test blocks in protection, control, and secondary-circuit applications. We are pleased to share that ODES TSBA and TSBE series test blocks have obtained UL certification for the United States and Canada. This certification represents an important step in supporting customers working on North American power projects, as well as international projects that reference North American electrical standards. For protection panels

Over the past decade, the most important change in the wind power industry has not only been larger turbines or longer blades. More importantly, wind farms themselves are evolving from individual renewable projects into system-level power infrastructure. A modern large-scale wind farm is no longer just a group of turbines standing in the wind. Behind it are high-voltage transmission, offshore substations, reactive power compensation, protection systems, remote operation, powe

By Yunxiang Zhang — Global Liaison, ODES Electric Introduction Signal-conditioning and isolation modules form the silent backbone of modern substation automation, ensuring that voltage and current signals are transmitted with precision and safety. These devices isolate, convert, and condition critical analog and digital signals, bridging sensors and protection systems while safeguarding operators and equipment from potential transients. As China accelerates its smart-grid m

By Yunxiang Zhang — Global Liaison, ODES Electric Introduction Time‑relays are fundamental to sequencing, interlocking, and delay logic in protection and control circuits. In MV/LV switchgear and substation automation, they gate operations such as breaker close/open, re‑energization, transfer switching, and alarm suppression. This page summarizes leading time‑relay manufacturers in China for 2026, focusing on signal accuracy, durability, and integration with power‑system co
