IEC 61757的本部分定义了设备的术语、结构和特性试验方法 采用偏振法的光学电流传感器。它涉及电流传感元件 仅限每个应用程序特有的附加设备，而非。通用规范 对于光纤传感器，IEC 61757中有定义。 由于每个用户所需的光纤电流传感器的规格不同 根据应用程序的不同，本文档未定义所需的性能值。 在根据特定要求设计传感器时，定义了所需的性能值 应用购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC 61757 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.All current amendments available at time of purchase are included with the purchase of this document.
