2 TRACTION MEASUREMENT SYSTEM TYPE TMS FOR 15 & 25 KVAC ROLLING STOCK

GENERAL INFORMATION

MAIN BENEFITSMAIN BENEFITS

Sécheron TMS is an evolutive Traction Measurement System dedicated to rolling stock applications and used for different functions including voltage detection, traction control, traction protection and energy measurement.The configuration proposed in this document covers the Voltage Measurement Function (VMF) as specified

in the standards EN50463-2/ IEC62888-2 for on board energy measurement. TMS measures the supply voltage of 15 kVAC and 25 kVAC traction systems, and transmits safe isolated and accurate signals to different on-board equipments.
