Railway applications. Fixed installations. d.c. switchgear. Measurement, control and protection devices for specific use in d.c. traction systems. Isolating current transducers and other current measuring devices | Status: Confirmed, Current

1 Scope This European Standard gives the requirements for isolating current transducers and other current measuring devices used in d.c. railway applications, fixed installations. This transducer is normally positioned between the sensor in the live switchboard conductor or rail and the secondary device, giving galvanic insulation between the input and the output.
