SEPCOS Control and Protection Relay

SEPCOS / CONTROL AND PROTECTION RELAY SEPCOS is a high-tech equipment which satisfies the most demanding safety requirements applicable to DC Traction Distribution Networks. SEPCOS is a powerful electronic system based on microprocessor technology. It is used as a protection and control unit of an outgoing feeder cubicle or rectifier breaker in DC traction related to transportation systems. The Protection Board (PRO board) development is based on the safety requirement of the railway standards EN50126, EN50128 and EN50129. SEPCOS is stand alone, modular, extending and easily adaptable by...

Bus connections Modularity and adaptability are key strengths of the SEPCOS. We developed this protection and control relay with the objective of getting the closest match to our clients needs. Sécheron can provide engineering support while elaborating a network regardless the type of communication and its architecture. SEPCOS is indeed open to all customers network and protocols: • IEC61850 including GOOSE • IEC60870-5-104 (-5-101) • DNP3.0 (Serial / Ethernet) SEPCOS is flexible in connectivity: copper cable (RS485, RJ45) or optical fiber. It also allows to meet the needs concerning...

SEPCOS / CONTROL AND PROTECTION RELAY Example of configuration with IEC61850 Applications Typical application of the SEPCOS: Touch Screen Display Control & monitoring High Speed Circuit Breaker Current (shunt or Hall sensor) Measuring amplifier MIU10 S-Web SEPCOS User software

With many control/command and protection functions, SEPCOS satisfies the needs of DC power traction networks such as outgoing feeder cubicle or rectifier breaker. SEPCOS is used for monitoring traction network segments and for logging events. It analyses the current gradient and voltages through cyclic measurements at the feeding point of the substation to the catenary. The measurements are made through an electrically isolated transducer (i.e. Sécheron’s MIU10 or VM10 measuring amplifiers). Protection Protection main features: Protection functions: • For each detection, the 3 following...

SEPCOS / CONTROL AND PROTECTION RELAY Graphic display and user interface A user-friendly interface is associated through a high resolution 7” color display, capacitive dual touch screen allowing easy and intuitive navigation. This device is equipped with 8 LEDs related to dynamic labels (color and text). It collects the information available from the SEPCOS. 7” capacitive dual touch screen It includes the modification of the SEPCOS parameters (Setting protections, Command parameters, etc.). Control orders Event list Protection parameters Control of the equipment (orders IN, OUT, RESET...

S-Web SEPCOS and trends S-Web SEPCOS is an integrated WebServer within each SEPCOS. Thus, it does not require any software installation on a computer. This interface is used to configure, visualize and analyze the SEPCOS data. The connection with the S-Web SEPCOS is done either through Ethernet cable or WiFi to access through a PC, a tablet computer or a smartphone. The S-Web SEPCOS operation only requires a web browser. S-Web SEPCOS allows: • Modification of the protection and command parameters of cubicles • Collection of the information recorded by the SEPCOS • Uploading and downloading...
