Study Notes
Commissioning of Electric Traction
- Electric traction introduction requires a clear action plan for high standards in departmental and contractor work.
- The organization for running the services must be prepared.
- Sections must be ready for prompt operation and efficient management as soon as 25 kV installations are energized.
Preparation by Open Line
-
Electrification work separation from Open Line (CEE) relieves them of detailed design, supervision, and execution.
-
The Open Line (CEE) plays a crucial role in timely installation takeover.
-
Organization creation with trained personnel is essential for operation and maintenance, beginning on the commissioning date.
-
Recruitment and training for operating and maintenance staff are necessary.
-
Close collaboration between Open Line Officers/staff and those during erection and adjustment is necessary.
-
Detailed inspections by lower and higher-ranking officers ensure work quality and identify rectifications.
-
Tests using rolling stock confirm functionality.
-
Administrative officers approve substation and OHE (Overhead Equipment) energization.
-
Final inspections (CRS) by electrical inspectors ensure proper commissioning and commercial service.
-
Post-commissioning operations and maintenance are essential.
Organization for Inspection and Taking Over
-
Officers/staff positions are created 6 months in advance.
-
A nucleus is created at the headquarters during zonal railway electrification,
-
Maintenance training schools should be created a year in advance to train staff for electric traction operation and maintenance.
-
Suitable staff from steam and diesel cadres are recruited and undergo conversion training a year prior to energization.
-
The organizational set-up should be enhanced three months prior to commissioning.
-
Expedite OHE and PSI depot and workshop facilities completion.
-
Essential tools, equipment and other resources are made available.
-
If a loco-shed is part of the RE (Railway electrification) project, staff will be in place six months prior to the receiving of locos.
-
Staff will organize facilities for maintenance equipment, jigs, and accessories.
Duties of Senior Divisional Electrical Engineer (TrD)
- The senior engineer is responsible for ensuring smooth construction work completion.
- The necessary accommodations (office and related facilities).
- Equipment, tools, spare parts and emergency vehicles must be available.
- Power supply systems are verified and officers are trained.
Duties of Senior Divisional Electrical Engineer (RS)
- Ensuring additional office/equipment accommodations and facilities, like loco sheds for inspection and maintenance
- Ensures the availability of full machinery, tools, testing equipment
- Necessary posts for operation and maintenance of rolling stock should be authorized.
- Training for steam/diesel drivers in electric rolling stock operation and related rules is arranged.
- Maintenance staff training and recruitment is ensured.
- Clearances, approvals and reports from responsible authorities must be obtained.
Commissioning of Traction Substations
- Power supply readiness and satisfactory substation and connected RC equipment inspection are pre-conditions.
- Essential communication facilities are ensured.
- Substations are usually commissioned well before OHE (Overhead Equipment) energisation.
Sanction of CEE and Electrical Inspector to the Railway
- Applications for design and layout approvals must be submitted (high voltage equipment is included, including traction substation and others)
- The application should include press cuttings of the public notification (and other relevant documents).
- Necessary clearances and documents needed for OHE, bonding/ earthing and safety instructions and safety precautions.
- Required data, test results, certificates (insulation resistance test results of OHE, data on sub/stations and safety related certificates).
- The sanction is issued in a specific form.
Notification Regarding Energization of OHE
- A notification regarding OHE energization is issued to several concerned authorities at least a month in advance.
- The notification mentions when the line will be energized (and related locations).
Application to CRS
- CRS sanction is required for electric traction introduction on the railway.
- Necessary certificates are also submitted to obtain the sanction.
- Certificates related to electrical work, rolling stock safety, and staff awareness of safety rules for electrified sections should be submitted to CRS.
Procedure for Energization
- Comprehensive inspections of the entire section are conducted during commissioning
- CRS, CEE and their associated officers will conduct a full inspection of the OHE, for operation and safety-related aspects.
- Train movements and staff are ensured to have relevant documentation
- Wide publicity should be given through the Press and posters in advance by the Railway to avoid accidents.
- Special safety precautions for energized parts of the overhead line.
Precautions for Progressive Energization of OHE
- Energization should be done progressively, maintaining separation between live and working areas or other safety measures.
- Safety measures for workers and passengers should be enforced and maintained when work is ongoing.
Final Inspection by CRS for the Introduction of Commercial Services
- Special trains are organized for inspection of safety and operational aspects by CRS, CEE, project managers, and divisional officers.
- CRS verifies knowledge of safety rules, operation, and related documentation by staff in different positions.
Sanction of CRS
- CRS issues an "all-concerned" message for commercial service start-up after trial operation success.
- Defective parts are rectified and proper handling of the OHE is ensured by the Open Line.
- Joint inspection confirmation of proper commercial operation is obtained.
Responsibility for Maintenance and Provisional Acceptance Certificate
-
Construction organizations take charge of OHE and power supply during the initial period until commercial operations launch.
-
Open Line's divisional officers are responsible for maintenance and operation after commercial service launch
-
A provisional acceptance letter is issued by the construction organization after maintenance and test completion.
-
Deficiencies in installations are reported and an extension is given until all the work is completed.
-
Contractor's responsibility during the guarantee period includes maintenance (along with support and assistance from trained personnel)
-
Defect reporting and investigation procedures for electrical equipment during the guarantee period are described in detail.
History Sheet
- Detailed maintenance of a history sheet for major equipment is recommended to track failures and required repairs.
