Rail and metro lines are powered by traction power substations (TPSSs) located within an appropriate proximity in order to ensure the best power performance and safety for the transportation system. It is preferable to locate the substations at the actual existing primary grid stations with a provision for adequately protected railway connection lines. The chapter summarizes the main criteria for establishing a grid connection strategy. If the primary power supply of a transformer and conversion substation is organized for cascaded connection (in‐out), then there should be a provision for interconnecting power line sections supported on separate pole structures. Voltage transformers (VTs) and current transformers (CTs), besides providing voltage and current measurements to the input lines, are necessary for giving various indications and status recordings as also required for metering purposes. The state‐of‐the‐art method is to proceed with the rating of the TPSS according to the last of the newly exposed methods. The chapter examines these methods more detail.
