GAMESA Product Lines We Repair
Our engineers are trained on the full GAMESA product range. Below are the major product families we service.
Gamesa G Series Turbine Control Electronics
Main power conversion and grid synchronization units in G80, G90, G114, and G132 turbines. Repairs involve resolving capacitor degradation, IGBT module failures, and firmware corruption in converter stacks that regulate 2-4.8 MW output to the grid.
Pitch and Yaw Control Systems
Hydraulic and electric pitch actuator drive units controlling blade angle and nacelle orientation. Common faults include servo proportional valve failures, position sensor drift, and CAN communication loss between pitch motors and main controller.
Gamesa Transformer and Medium Voltage Switchgear
Step-up transformers, circuit breakers, and medium-voltage disconnects integrating turbine output to substation networks. Repairs address insulation degradation, tap changer failures, and arc suppression coil malfunctions common in monsoon-prone Indian locations.
SCADA and Wind Farm Supervisory Systems
Remote monitoring, data logging, and alarm management modules that communicate turbine health across wind farms. Issues include Ethernet port failures, real-time clock drift, SD card corruption, and communication protocol layer breakdowns.
Gamesa Converter and Power Module Units
Three-level Neutral Point Clamped (NPC) and modular multilevel converter stacks for grid compliance. Repairs include component-level rework of capacitor banks, diode bridges, and snubber networks suffering from thermal cycling and salt-corrosion damage in coastal wind farms.

Common GAMESA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GAMESA equipment arriving at our workshop.
- ✓Converter IGBT Module Thermal Runaway and Derating — Gamesa turbines in high-ambient, high-humidity regions (coastal Tamil Nadu, Gujarat) experience accelerated solder joint fatigue in IGBT modules. Thermal cycling combined with salt-laden air corrosion reduces heat dissipation efficiency, triggering power-limiting error codes.
- ✓Pitch Drive CAN Communication Loss and Blade Asymmetry — Pitch control systems rely on real-time CAN messaging between the main turbine controller and each blade pitch motor. Moisture ingress into CAN terminator resistor modules or degraded shielded cable insulation in the rotor slip-ring assembly causes intermittent frame loss, resulting in blade angle mismatch.
- ✓Yaw Gearbox Encoder Offset and Nacelle Misalignment — The yaw motor encoder in Gamesa turbines drifts due to repeated mechanical play in the gearbox and electromagnetic noise coupling from the main converter onto analog encoder signal lines. This causes gradual nacelle misalignment, increasing aerodynamic losses and vibration.
- ✓Transformer Insulation Breakdown and Oil Contamination — Monsoon humidity and thermal cycling in Indian wind farms cause moisture absorption into transformer insulation paper and oil. Particulate contamination from salt spray and dust accelerates dielectric breakdown, particularly in step-up transformers rated 1000+ kVA.
- ✓SCADA Data Logger Card Corruption and Timestamp Loss — Gamesa SCADA modules use SD memory cards for historical energy yield and fault logging. Power supply brownouts, electrostatic discharge during maintenance, and inadequate write-protect tab management cause file system corruption and RTC (real-time clock) battery failure, losing timestamped operational data.
- ✓Grid Filter Unit Capacitor Bank ESR Rise and Harmonic Distortion — Gamesa's grid output filters use aluminum electrolytic capacitor banks that degrade under high-temperature and high-current conditions common in India's dry, hot climates. Rising equivalent series resistance (ESR) reduces filter effectiveness, causing harmonic injection into the grid and SCADA alarm generation.

Frequently Asked Questions — GAMESA Repairs
Do you repair Gamesa wind turbine electrical equipment anywhere in India?+
Yes. Synchronics repairs Gamesa converter systems, pitch/yaw drives, transformers, and SCADA modules across all Indian wind farms. We offer emergency same-day pickup from major hubs (Mumbai, Chennai, Hyderabad, Pune, Ahmedabad) and work with pan-India crane logistics. Our Vadodara facility has test benches rated for 6.6kV three-phase testing and real-time SCADA simulation.
What is the typical turnaround time for Gamesa converter module repair?+
Synchronics typically completes converter diagnostics within 24 hours and component-level repair within 3-5 working days, depending on IGBT submodule and capacitor availability. High-urgency turbine faults receive expedited service; we hold common Gamesa replacement modules in stock. Full factory testing and certification takes an additional 2 days.
Can Synchronics repair Gamesa pitch and yaw systems on coastal wind farms?+
Absolutely. Coastal installations across Tamil Nadu, Gujarat, and Maharashtra face accelerated salt-corrosion damage to pitch encoders and yaw slip-rings. Synchronics specializes in rework and re-sealing of these units. We use conformal coating on encoder PCBs and upgraded marine-grade connector assemblies to extend service life in corrosive environments.
Do you offer Gamesa transformer oil analysis and reconditioning?+
Yes. Synchronics provides transformer oil sampling (per IEC 60422), Karl Fischer moisture testing, dielectric breakdown strength (DBS) analysis, and particle contamination grading. For failed units, we perform vacuum dehydration cycles, oil flushing, and complete fluid replacement with Gamesa-approved mineral oil. We also pressure-test welds and gasket integrity post-service.
What warranty do you provide on repaired Gamesa equipment?+
Synchronics issues a 12-month on-site warranty for all Gamesa electrical system repairs, including converter modules, control drives, and SCADA units. If a component fails during warranty, we provide replacement or repair at no charge. Extended 24-month warranties are available for critical wind farm equipment; spare parts availability is guaranteed for 5 years post-repair.
How do I send my GAMESA 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 GAMESA 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 GAMESA 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 GAMESA 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.
