The integration of China's transformer industry and energy storage industry is driving the transition of power sensing systems towards high precision, intelligence, and full stack localization. In the field of electrochemical energy storage, fiber optic transformers and Rogowski coils have fully replaced traditional electromagnetic devices with advantages such as non-magnetic saturation, wide bandwidth, and resistance to electromagnetic interference, achieving high-precision acquisition of battery cluster charging and discharging current ± 0.2% F.S., supporting BMS to achieve millisecond level SOC/SOH estimation and overcurrent protection, with a response time of less than 4 μ s. Leading companies such as Siyuan Electric, Pinggao Electric, and Xuji Electric have built an integrated solution of 'transformer+PCS+EMS'. The market size of domestic intelligent transformers will exceed 20 billion yuan in 2024, with a compound annual growth rate of over 65%. The standard system is enforced, and GB/T 34131-2023 and GB/T 46261-2025 specify thresholds for current sampling error, temperature response (≤ 16min at 70-90 ℃), gas monitoring, etc., promoting the evolution of sensing equipment from single measurement to multi parameter fusion. Typical projects, such as Gansu Linze 300MW/1200MWh independent energy storage power station and China Southern Power Grid deep storage power station, rely on 5G+edge computing to achieve real-time return of current and voltage data and AI anomaly diagnosis, and support power grid frequency modulation and peak shaving and spot power trading. Transformers have been upgraded from 'measuring elements' to safe nerve endings and intelligent decision-making entrances for energy storage systems, accelerating the construction of a 'perception control optimization' closed-loop.
