A presentation of how BART's traction power system worksTRANSCRIPT
Traction Power Program Basics
Traction Power Engineering Program Summary
Sub Program & Project Example Operational Function
1. Substation Replacement Replace 28 substations
Converts 34.5KV AC to 1000v DC power
2. 34.5KV AC Cable Replacement Replace PIPE cable with EPR cable A Line and M Line
Cables distribute the AC power to the substations
3. Traction Power Controls MPR, Rectifier Rehab, Blocking
Provide safety protection circuits and OCC controls and alarms
4. 3rd Rail System Improvements 3rd Rail Replacement K & A Lines
Delivers power to the train
5. Gap Breaker Station Replacement- 14 each
Provides power redundancy to 3rd rail sections
6. Unplanned Renovations – Transformer Replacement, Disconnect
Switches
Emergency repair contracts to transition to reactive projects
Bulk Supply Station 4 each
Switching Station 8 each
Traction Power Substation 62 each
Gap Breaker Station 48 each
34.5KV AC Cable 210 miles
3rd Rail 240 miles
Power Transformers 116 each
