What are TRD batteries? power supply v dc

Traction distribution in railway: Indian Railway Traction Distribution department is responsible for maintenance & operation of overhead equipment, power supply installations, sectioning post & remote control to supply necessary electric power to electric locomotive MEMU.

What is traction supply? What does traction mean in Railway?

Traction power supplied from various feeding post and traction sub-station is controlled by Traction Power Controller (TPC) from Remote Control Centre (RCC).

The Traction Distribution battery is crucial to the power supply system.
Batteries and battery chargers are installed at the following locations on electrified sections.-

  • Traction Sub-stations –
    110V, 200Ah.lead acid cells for control, protection and indication circuits.
  • Switching Stations –
    110V or 72V, 40Ah lead acid batteries for operation of circuit breakers and interrupters and motor-operated isolators.
  • Remote Control Equipment –
    Batteries of suitable voltage and capacity at remote control centre, traction sub-station and switching stations.
  • normal traction distribution on

To reduce number of batteries at TSS/SS the remote control equipment is now being connected to the battery of TSS/SS.
In all cases, mains-operated battery-chargers are provided with facilities for either trickle charge or boost charging. Battery charger ratings should be determined by the capacity of the battery.

Designed by Dr Wieland Rusch of Germany – Manufactured with precision and pride in India, we make the complete Railway Traction Distribution batteries and all its components in house ensuring a high level of quality without having to depend on outside vendors.

Battery Mistakes All TRD Battery Owners Need To Avoid!

Do not mix new batteries with old batteries

Traction Distribution Battery reconditioning: often reconditioning an old battery can become quite a costly affair if you keep replacing dead batteries one by one; even the new battery will drain out rapidly as the old batteries tend to draw more out of the new one. 

Traction Distribution replacement batteries: Sometimes it becomes imperative that an unused set of TRD batteries have not been installed for a very long period, say 2 years or more. Then it is best to have an expert from the company visit you to have a thorough inspection of the TRD batteries after a complete charge, compare the cell voltage, specific gravity to decide the state of charge & whether it needs to be replaced or it is safe to use.

Avoid any sort of additives or desulfation methods

How to recondition Traction Distribution batteries? Batteries are electro-chemical devices. All chemicals have a half-life period beyond which regeneration with chemical additives or desulfators for batteries have little effect if any temporary. 

The normal mode of failure of Traction Distribution batteries is usually due to grid corrosion if the lead alloys are not designed properly. Desulfators cannot repair corroded grids.
