Sécheron has been developing and manufacturing safety devices for DC traction systems for the railway industry for decades. We have drawn upon our extensive experience with DC traction systems and the related industry standards to develop our newest generation of protection relays, SEPCOS.

Our SEPCOS line is available in a wide range of configurations to meet your DC traction feeder control and protection needs. Our SEPCOS PLC and SEPCOS Gateway products bring additional connectivity and data logging capabilities to the control, command and supervision of your DC traction power substations.

Our KEOPS system controls and supervises all substation equipment via a local SCADA and provides the gateway to the line’s overall energy SCADA.

Finally, our SCMS (Stray Current Monitoring System) prevents corrosion caused by stray currents on railway equipment and non-railway installations.
