Polifemo is an integrated voltage and current measurement transducer that is suitable for railway traction systems operating at nominal system voltages of 25 kV (50 Hz) and 15 kV (16.66 Hz). Polifemo is accurate enough to be used for the catenary Voltage Measurement Function (VMF) and Current Measurement Function (CMF) to EU standards for energy measurement on board rail vehicles. It is also suitable for rooftop installation.

Polifemo can be delivered as a stand-alone device for rooftop installation by car builders and operators. It can also be provided as part of Sécheron Hasler Group’s comprehensive Energy Management System, which also includes the REM102 Energy Meter with DHS and DCS.

All of our products are backed by HaslerRail experts, who provide recommendations and support throughout the project lifecycle, and Sécheron Hasler Group’s worldwide network of service locations for assistance throughout the product lifetime.
