Study Notes

Operation of Traction Power Control

Remote Control Centre (RCC) manages electrified system switching
One Traction Power Controller (TPC) is in charge per shift
Assistant TPC (ATPC) assists if needed
TPC responsible for switching accuracy and logbook entries
No unauthorized personnel allowed with control switches.
TPCs must know all safety regulations, electrical systems and relevant paperwork.
Entry to RCC requires authorization
No shift changes or hour variations without senior approval.

Shift Duty

Shift duty register tracks all shift changes and relevant information; shutdowns, power blocs, defects, any important notes for oncoming TPCs.
Incoming TPCs receive the register and mimic diagram, review previous shift's work and sign off to show that handover is complete.

Repair and Adjustment of RC Equipment

TPCs may not repair equipment other than switching operations, as this is the job of specific personnel, but any observed defects must be reported.
No remote control or power system work allowed without authorization.
Tested and approved equipment is necessary.

Switching Operations

Careful and deliberate switching operations are crucial due to the fast speeds.
Simultaneous operation of many switches must be avoided.
Close communication with Section Controller is required.

Telephone Calls

TPC or ATPC respond to RCC calls promptly
Emergency calls prioritize over others.

Log Book

Maintains minute-by-minute record of switching operations, power supply interruptions, unusual occurrences, messages, special instructions.
All documented in chronological order.

Maintenance Staff Movements

TPC keeps track of maintenance staff's location for emergency situations so the nearest personnel are quickly notified.

Time Checking

TPC checks the time accuracy at 1600 hours each day using the time signal.

Alarm Circuits

TPC tests alarm circuits at each shift change.
Uses mimic diagram panel.

Emergency Generator

A 415/240V, AC, 50Hz, 3-phase Diesel Engine Driven Generator set is available for essential loads in the case of mains failure.
Training is given for setting it up.

Chief Traction Power Controller (CTPC) Duties

Reviews OHE failure reports, prepares reports for the AEE/DEE including stats, and ensures maintenance schedules are observed.
Monitors traffic delays and consults the Chief Controller to ensure accuracy of records.
Maintains contact with other TPCs, staff and relevant figures.
Supervises proper maintenance of log books.
Ensures adherence to rules and procedures for all TPC and ATPC personel

Traction Power Controller (TPC) Duties

Manages 25 KV power supply
Familiarity with all traction power installations and sectional arrangements
Manages shifts and communicates with all relevant personnel and figures in case of incidents
Records details regarding all trains, including important points and instructions.
Handles power blocks and advises, notifies necessary personnel and higher-ups.
Monitors circuits, maintains registers, and ensures efficient station operation.

Fault Localization

Control cards guide switching operations to quickly locate faults.
All personnel must be familiar with the control cards, ensuring a consistent and fast response to fault locations.

Faulty Section Isolation

TPC isolates faulty sections promptly ensuring that healthy sections' power is restored.
Suitable procedures must be followed when dealing with such issues.

Section Controller Advice

TPC promptly notifies the Section Controller about any faults, following safety precautions.
TPC gives the required information about the anticipated time in locating the fault and restoring power.

Obstructions to Track

The TPC must switch off power to the affected tracks should an obstruction occur.
