T/ZSA 175-2023 Fully Optical Current Measurement Device

Scope

Scope: This document specifies the functions and components, usage conditions, technical requirements, test methods, inspection rules, and marking, packaging, transportation, and storage of all-fiber current measurement devices. This document is applicable to the use, inspection, and transportation of all-fiber current measurement devices. Main technical content: This document involves the patents "An All-Fiber Current Transformer with Double Closed-Loop Control" (National Invention Patent ZL200810226866.9) and "An External Integrated All-Fiber Current Transformer for Isolation Breakers" (National Invention Patent ZL201410844505.6). The patent "An All-Fiber Current Transformer with Double Closed-Loop Control" solves the problem of optical power fluctuation caused by temperature and vibration in the optical path, which is conducive to the stability and reliability of the optical path system and lays a foundation for the engineering application of all-fiber current measurement devices. The patent "An External Integrated All-Fiber Current Transformer for Isolation Breakers" solves the problem of integrating all-fiber current measurement devices with isolation breakers and provides a reference for the productization of all-fiber current measurement devices, including design, installation, and operation and maintenance. The implementation of the technical requirements in Chapter 6 of this document uses the key technologies mentioned in the above two patents.
