1 Scope
This part of IEC 61757 defines the terminology, structure, and performance characteristics of fibre optic
voltage sensors using a polarimetric measurement method. The document specifies test
methods and procedures for measuring key performance parameters of these sensors.
It addresses only the voltage sensing element and not the additional devices that
are unique to each application.
The document does not specify the required performance values of optical polarimetric
fibre optic voltage sensors, because these specifications depend on the designated
application of the sensor and are typically defined by the user of the sensor. The
required performance values are usually defined when designing a sensor for a specific
application.
