For 600 V dc line for tramcars

  • For 600 V dc line for tramcars the track is connected to negative of the supply.
  • In many tramcar systems that use a 600 V DC power supply, the track is connected to the negative (or "return") terminal of the power supply.
  • The positive terminal of the power supply is typically connected to overhead wires, which provide the power to the tramcars through a pantograph or a sliding shoe.
  • The connection of the track to the negative terminal of the power supply creates a complete circuit for the flow of electric current, allowing the motors in the tramcars to operate.
  • This system is known as a "return circuit" or "ground return" system.
  • The use of a DC power supply in tramcar systems allows for efficient operation of the motors and precise control of the tramcar speed and acceleration.
