Traction Power Substation

A traction power substation (TPSS) is essential to an electrified railway system. It provides electrical power to power the trains and is responsible for converting AC power from the grid to the DC power required by the trains.

The TPSS usually consists of two main components: the rectifier unit and the transformer unit. The rectifier unit is responsible for converting the AC power from the grid into DC power. The transformer unit decreases the voltage to the required level for the train's electrical systems.

One of the critical components of a TPSS is the transformer. The transformer is responsible for stepping down the high voltage AC power from the grid to a lower voltage DC power required by the trains. These transformers are specially designed to handle the high currents required by the trains and are often filled with oil to help dissipate the heat generated during operation.

Another essential component of a TPSS is the rectifier unit. The rectifier unit is responsible for converting the AC power from the grid into DC power. It consists of a series of diodes that allow current to flow in only one direction, effectively converting the AC power to DC power.

The TPSS is usually located near the railway track, and the electrical power is distributed through overhead lines or a third rail. The power is delivered to the train through a pantograph, which is a mechanism that collects power from overhead lines or third rails.

The TPSS is a crucial part of the electrified railway system, as it provides the necessary power for trains to run efficiently and effectively. Without TPSS, trains would have to rely on internal combustion engines, which would increase operating costs and have negative environmental impacts.
