BS EN IEC 61757-4-3:2020

What is BS EN IEC 61757-4-3 about?

BS EN IEC 61757-4-3 discusses the polarimetric method for the fibre optic current sensor. BS EN IEC 61757-4-3 defines terminology, structure, and a characteristic test method of an optical current sensor using the polarimetric method.

As the specifications of optical polarimetric fibre current sensors required by each user vary depending on the applications, BS EN IEC 61757-4-does not define the required performance values.

The required performance values are defined in BS EN IEC 61757-4-3 when designing a sensor according to the specific application.

Note: BS EN IEC 61757-4-3 addresses the current sensing element only and not the additional devices that are unique to each application.

Who is BS EN IEC 61757-4-3 for?

BS EN IEC 61757-4-3 on electric current measurement is useful for:

• Optical current sensors manufacturers
• Electrical appliances manufacturers
• Quality control laboratories

Why should you use BS EN IEC 61757-4-3?

BS EN IEC 61757-4-3 provides a polarimetric method for the fibre optic current sensor to measure direct electric current. BS EN IEC 61757-4-3 defines terminology, structure, and a characteristic test method of an optical current sensor using the polarimetric method which helps to develop new optical current sensors and ensure the evaluation, performance, characteristics of fibre optic sensors.

BS EN IEC 61757-4-3 makes it possible to design the sensor efficiently and properly and to transfer the sensor smoothly from a supplier to a user by settling issues a set of methods is summarized in BS EN IEC 61757-4-3 for evaluating the performance and characteristics of optical current sensors.
