Introduction
AC Traction - Distribution is one of the most important aspects of Electrified Railways that ensures a safe,
modern and cost effective Railway technology to cater the growing demand of passenger and freight
traffic on Indian Railways with excellence. The main vision behind the creation of this department is to
minimize the outgoing of foreign exchange for purchase of Diesel over Indian Railways.
The main goal of TRD department is to achieve constant & uninterrupted 25 KV AC power
supply through OHE for safe passage of trains through the stations. This is also a system
which eliminates the human failures while dealing trains. The design of different types Traction
installation used is such that to ensure a fail safe operation.
Different electrical equipments like- Transformers, Circuit Breakers, CT, PT, BM, OHE Masts, Conductors,
Insulators, Bonds etc. are integrated in such a manner to ensure safety & reliability of the system
through continual improvements in maintenance.
History
The TRD organization is the heart of Electrical department. This organization was formed in the year
2001-02 in South Eastern Railway, Ranchi division. The Complete tracks of Ranchi division (Except
Ranchi- Lorhardaga section) were electrified with 25 KV AC traction in the year 2001-02. Ranchi-
Lohardaga-Tori section (120KM)has been electrified in the year 2018-19.The electrified Route Kilometer
and Track Kilometer of Ranchi division is 485.31 RKM and 785.68 TKM respectively. Total staffs on roll
are 216, Men/TKM = 0.27.

Infrastructure
Traction Sub-Stations & Switching Posts
The power supply to the entire section over Ranchi Division, is presently fed by Six Traction Sub-Stations
(TSS) out of which four TSSs namely Lohardaga, Tatisilwai, Lodhma, Bakaspur, and Bano are receiving
power supply from JSEB and rest one TSSs namely Muri is receiving power supply from DVC. In order
to bifurcate the OHE into sector and sub-sector for proper isolation for maintenance or during
emergencies 33 nos. switching stations have been provided out of which 12 are SP and rest 21 are SSP.
Maintenance Depots
There are total Ten Maintenance depots to maintain the Tr-D assets, out of which Six depots are carrying
out maintenance of OHE assets and rest four depot maintains PSI assets. This organization setup
facilitates the efficient management of resources.
Break-down vehicles
The deployment of Nine Tower Wagons and four hired Trucks to various depots are done on the basis
of quantum of work and geographical configuration of their jurisdiction. Special care has been taken while
deploying eight wheeler Tower Wagon at Hatia, Muri,Lohardaga and Bano keeping in view the
maintenance of all section and its efficient utilization/assistance to other depots as and when required.
Remote control of Power Supply Installations through SCADA system
One Traction Power Control Board is now functioning in the divisional office at HTE for monitoring &
controlling the OHE power supply over division. PC based Supervisory Control and Data Acquisition
system has been commissioned for operation and monitoring of power supply equipment ’s. All the
traction SP and SSP in Ranchi division are unmanned and are being monitored through PC based
SCADA system.
The Remote Control Unit is monitoring the system for the trouble free functioning of the SCADA systems.

Innovation & Initiatives taken towards system improvement
Apart from the regular maintenance work, the division has taken up various innovative works for implementation of advance technologies like :
Energy conservation
Capacitor banks have been installed at all traction sub-station of RNC -division a move towards energy
conservation.
Introduction of Advance Technology
Thermography of Traction installations as a preventive measure to detect the hot spots in Tr-D
installations thermography checking by Thermal Vision Camera is being done, hence any
defects/discrepancies can be attended well before the unusual occurrences.
GPS based OLIVER-G Current collection system
In order to monitor the smooth negotiation of pantograph on contact wire and occurrences of heavy
flashes during passage of pantographs, the GPS based OLIVER-G Current collection system is being
used as a preventive measure.
The OLIVER Make RT Software supplied with the unit identifies sparks in real time and save them as
images with locations as well as in video format. These images can be analyzed to recognize the type of
spark with its location.
Tan delta (Tan δ) testing
Tan delta test kit is being used for checking leakage current of bushings of power transformer, Current
Transformer and Potential transformer.
Leakage current monitoring of Lightening Arrestor
Leakage current checking are being done to diagnosis the healthiness of lightening arrestors.
Logistic solution for overhead bunker loading in Electrified section
A special arrangement has been made at Rajrappa Washery siding by Providing 25 KV Traction
underneath the chute of loading Bunker to facilitate passing of Electric Loco in Power On condition,
loading can thus be done in EOT position.
Stagger checking and video recording of section with the help of GPS based OLIVER-G
In this system, stagger checking is being done with the help of GPS based OLIVER-G. The actual stagger
and accurate location of traction masts are displayed on Laptop and also continuous video recording of
stagger of entire section is done. By this system stagger checking is being done by one person only and
later is can also be analyzed in the Depot/office.
Model OHE at important OHE Depot
Model OHE has been erected at major OHE Depot for field training to artisan staff. Various mock drills are
being organized among staff for early Breakdown restoration.
Annual Achievements 2020-21

Traction Energy bills after commissioning of RMT/SP are approx. Rs.36 Lakhs
each in the month of Oct. & Nov.2020 and Rs. 40 Lakhs in the month of
Dec.’2020 in comparison with Sept.’2020
