CEGELEC ALSTOM Product Lines We Repair
Our engineers are trained on the full CEGELEC ALSTOM product range. Below are the major product families we service.
CEGELEC ALSTOM Traction Converters
Rectifier and inverter modules for AC/DC traction systems in locomotives and metro trains. Common issues include thyristor failures, capacitor degradation, and cooling system faults affecting power delivery.
Railway Signalling and Control Systems
Programmable logic controllers and signal processing units for track control, interlocking, and train management. Repairs address processor failures, communication card defects, and memory corruption.
Power Electronic Modules
Modular power supply and gate drive units for industrial and traction applications. Prone to component aging, insulation breakdown, and IGBT switching failures under high thermal stress.
Pantograph Control Electronics
Servo controllers and current collectors for overhead line contact in electric trains. Failures include servo amplifier burnout, encoder signal loss, and mechanical wear in contact arms.
Auxilliary Power Systems (APS)
Onboard auxiliary converters supplying 400V three-phase, 230V single-phase, and 24V DC to train systems. Subject to short-circuit protection trips, transformer overheating, and DC regulation drift.

Common CEGELEC ALSTOM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CEGELEC ALSTOM equipment arriving at our workshop.
- ✓Thyristor and IGBT module short-circuit failure — CEGELEC ALSTOM traction converters experience thyristor junction degradation and gate oxide breakdown under repetitive high-current switching in locomotives. Thermal cycling and moisture ingress accelerate failure in Indian climate conditions.
- ✓Railway signalling PLC memory corruption — ALSTOM MICRELEC and IXL controllers lose program memory and lose interlocking logic due to power supply glitches, electrical surges, or battery backup depletion in remote lineside cabinets exposed to weather.
- ✓Pantograph servo amplifier open-circuit breakdown — CEGELEC ALSTOM pantograph control servo boards fail when contact arm current spikes cause output FET and driver IC burnout. Moisture in overhead line environments and poor cable shielding worsen this.
- ✓Auxiliary power converter regulation dropout — ALSTOM APS 400V and 24V units drift out of regulation when transformer core saturates, feedback resistors drift, or optocoupler LEDs dim due to age and heat in Indian locomotive cabins.
- ✓Power supply capacitor bank bulging and leakage — Electrolytic capacitors in CEGELEC ALSTOM power modules swell and fail due to prolonged operation above 50°C in Indian industrial plants and engine sheds, combined with ripple current stress.
- ✓Communication interface card CAN/Ethernet corruption — ALSTOM signalling system communication cards lose protocol lock and message integrity due to surge damage from lightning, improper cable termination, or EMI from adjacent power equipment.

Frequently Asked Questions — CEGELEC ALSTOM Repairs
Do you repair CEGELEC ALSTOM railway and industrial equipment anywhere in India?+
Yes. Synchronics is the authorized independent repair partner for CEGELEC ALSTOM across India. We repair traction converters, signalling controllers, pantograph systems, and auxiliary power supplies. Pan-India door pickup available from Mumbai, Delhi, Pune, Hyderabad, Bangalore, Chennai, Ahmedabad, and all metros. All equipment serviced at our ISO 9001 certified Vadodara facility with ALSTOM-trained engineers.
What is the typical repair turnaround time for CEGELEC ALSTOM traction converters?+
Standard repair of CEGELEC ALSTOM thyristor and IGBT modules takes 7-10 working days including thermal cycling and bench testing. Urgent repairs for critical Indian Railways and metro applications are prioritized within 48-72 hours. We maintain stock of common spares — power semiconductors, capacitors, and gate drive boards — to minimize downtime.
Can you recover program data from a failed ALSTOM railway signalling PLC?+
Yes. Synchronics successfully recovers and restores program memory from CEGELEC ALSTOM MICRELEC, IXL, and CBTC controllers even after complete memory loss. We use ALSTOM-certified extraction tools and cross-reference against Indian Railways design standards. Recovery rate is 95%+ for controllers with intact flash memory chips.
Do you offer CEGELEC ALSTOM equipment calibration and compliance certification?+
Yes. After repair, all CEGELEC ALSTOM equipment undergoes full functional calibration, thermal testing, and dynamic load verification. We issue calibration certificates referencing ALSTOM standards and Indian Railways safety requirements. Equipment is stress-tested to 110% rated load to ensure reliability in Indian industrial and railway environments.
What warranty do you provide on CEGELEC ALSTOM repairs?+
Synchronics provides 12-month parts and labour warranty on all CEGELEC ALSTOM repairs, including traction converters, signalling systems, and power modules. Extended 24-month warranty is available for critical Indian Railways applications. We also offer on-site support and preventive maintenance contracts for plants and railway depots.
How do I send my CEGELEC ALSTOM unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a CEGELEC ALSTOM drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on CEGELEC ALSTOM repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your CEGELEC ALSTOM unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
