Voltage Transducer For Monitoring And Protection Of 3Kvdc Railway Traction Lines (Rfi Spec. Ifs363a)

Voltage transducer PM0984A allows to monitoring 3KVdc railway traction line.

The system is composed of two units: a selfpowered HV Transducer, and a Receiver, the units are connected through an Optical Fiber link.

The advantages of this solutions are: better safety, great EMI immunity and opportunity to place the receiver at great distance.
