[中文适用范围]： 本部分IEC 61757定义了使用偏振法的光学电流传感器的术语、结构和特性测试方法。它仅涉及电流传感元件，而不涉及每种应用特有的附加设备。光纤传感器的通用规范在IEC 61757中定义。由于每种用户所需的光学偏振光纤电流传感器的规格因应用而异，本文档未定义所需的性能值。所需的性能值在根据特定应用设计传感器时定义。 [外文原描述]： IEC 61757-4-3: 2020 defines terminology, structure, and a characteristic test method of an optical current sensor using the polarimetric method. It addresses the current sensing element only and not the additional devices that are unique to each application. Generic specifications for fibre optic sensors are defined in IEC 61757. As the specifications of optical polarimetric fibre current sensors required by each user vary depending on the application, this document does not define the required performance values. The required performance values are defined when designing a sensor according to the specific application. The contents of the corrigendum of June 2022 have been included in this copy.
