Traction Power System

Introduction:

Traction power systems are specialized electrical networks designed to supply energy to rail transport systems, ensuring continuous and efficient train operation. These systems include power generation, distribution, and conversion technologies that enable trains to operate on electrified tracks. They encompass different supply methods, such as direct current (DC) and alternating current (AC), along with various track electrification techniques.
