Earthing and Bonding System in viaduct

S No Earthing System Connection type

1. Buried Earth conductor(BEC)

35 sq mm copper wire

Running from Koyambedu to St. Thomas mount

on Up and Down line

In the cable tray.

2. Aerial Earth wire93.0 sq mm ACSR conductor

Running from Koyambedu to St. Thomas mounton Up and Down line

And supported on all mast/DA/Portals

3. Earth electrode for Viaduct The viaduct is supported at regular interval by

piers. In each viaduct pier some dedicated

reinforcement rods are taken from the top to the

bottom of the pier. This acts as earth electrode for

the pier. This is connected to the viaduct segment

and parapets reinforcement rods .The same is

connected to BEC at an interval of 200 m

4. RETURN CURRENT BUSBAR(MAIN

LINE)

Near feed in points

5. MAIN EARTH TERMINAL On either end of the station and in between

stations

6. EARTHING CONNECTION

BETWEEN BUSBAR AND BUSBAR

Connection between the Main earth terminals

7. EARTHING CONNECTION

BETWEEN BUSBAR AND TRACK

At feed in points

8. CONNECTION BETWEEN RAIL-RAIL At either end of each station

9. CONNECTION BETWEEN BUSBAR -

BEC

On either end of the station and in between

stations

10 Mast to BEC connection On either end of the station and in between

stations

5. BEC to traction rail connection At S bond locations

6. Up line rail to down line rail At regular interval of 200 m.

7. Hand rail to BEC At regular interval of 200 m.

8. Platform reinforcement to BEC-
