ANSALDO Product Lines We Repair
Our engineers are trained on the full ANSALDO product range. Below are the major product families we service.
Ansaldo Turbine Generator Control Systems
Automatic voltage regulators (AVR), excitation controllers, and synchronization modules for thermal and hydro-electric generators. Common issues include failed thyristor modules in excitation circuits, aging capacitor banks in voltage sensing stages, and intermittent gate-drive failures in static exciters.
Ansaldo Marine Propulsion Electronics
Diesel engine control modules, fuel injection governors, and main switchboard controllers for naval and commercial vessels. Repair focus areas include governor fuel rack linkage electronics, slow-speed diesel control modules, and marine-duty IGBT power stages in propulsion frequency converters.
Ansaldo Industrial Protection Relays
Static and electromechanical protection relays for generator protection, bus-bar protection, and feeder overcurrent/distance protection in thermal and hydro power stations. Common faults include failed current transformer input circuits, worn relay contact buffers, and software/firmware corruption in numerical relay variants.
Ansaldo Electrical Auxiliaries and Panel Components
Battery chargers, DC supply modules, and auxiliary control electronics for switchyard installations and generator-unit auxiliary systems in power plants. Repair services include transformer winding insulation testing, bridge rectifier replacement, and electrolytic capacitor reformation for aged installations.
Ansaldo Governor and Load Control Systems
Electro-hydraulic governors, load-sharing modules, and boiler-turbine coordination systems for power generation facilities. Defects typically manifest as instability during load transients, amplifier saturation in feedback loops, and solenoid coil burnout in hydraulic servo-valve pilot stages.
Ansaldo Fire Detection and Safety Electronics
Marine fire alarm systems, thermal and smoke detection modules, and emergency shutdown electronics for ship engine rooms and power plant auxiliary spaces. Repair includes sensor calibration drift correction, detector module reprogram, and replacement of corroded salt-spray component substrates.

Common ANSALDO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ANSALDO equipment arriving at our workshop.
- ✓Ansaldo AVR thyristor module thermal runaway — Thyristor junctions in Ansaldo EX-3000 and AVR-2500 series degrade under sustained reactive load swings or inadequate cooling airflow in switchyard enclosures, leading to gate-drive threshold shift and uncontrolled gate current.
- ✓Ansaldo SPAJ/SPAM relay contact chatter and spurious trips — Electromechanical relay armature pivot wear and springset fatigue in high-vibration switchyard environments cause intermittent contact bounce, falsely triggering generator or line protection. Salt-spray corrosion accelerates failure in coastal thermal power plants.
- ✓Ansaldo MCP-500 marine diesel engine fuel rack control instability — Potentiometer wiper corrosion in fuel rack position feedback transducers aboard naval vessels and cargo ships causes erratic governor response during maneuver operations. Inadequate enclosure gasket sealing allows bilge water ingress.
- ✓Ansaldo DCS-100 DC supply module capacitor bank failure and voltage sag — Electrolytic bulk capacitors in Ansaldo power supply modules installed in 1990s-2000s thermal plants age and dry out under continuous 40-50C switchyard temperatures, losing capacitance. Insufficient design margin during monsoon load peaks causes voltage ripple.
- ✓Ansaldo EHG-2000 electrohydraulic governor hunting and oscillation — Servo-valve pilot stage solenoid coil insulation breakdown in humid, salt-laden marine engine rooms allows partial coil shorts, reducing magnetic force symmetry and causing control loop instability during governor droop correction.
- ✓Ansaldo SPAM 150 distance relay secondary winding saturation and relay overreach — CT (current transformer) secondary winding saturation occurs on high-impedance utility networks or during external fault transients, causing SPAM numerical relay to overreach and misoperate. Legacy SPAM models lack flux-limiting design.

Average turnaround for marine diesel controller repair is 5-7 business days with sea-trial acceptance documentation.
Can you repair Ansaldo SPAJ/SPAM generation and protection relays?+
Yes. Synchronics maintains full repair capability for Ansaldo SPAJ 130/140 generator protection relays and SPAM 150/160 distance relays used across NTPC, BHEL, and private thermal stations. We perform contact replacement, armature spring restoration, relay coil winding insulation testing to 10kV, and firmware reprogramming for numerical variants. All relays are tested on our Ansaldo-standard relay test set before return to power plant service.
How quickly can Synchronics repair an Ansaldo EX-3000 excitation system that has failed in my power plant?+
Field diagnosis and fault isolation typically requires 24-48 hours depending on site accessibility. If thyristor modules or AVR control cards are faulty, replacement modules can be expedited from inventory. Full excitation system repair and commissioning turnaround is typically 10-14 days. For critical NTPC or state utility projects, Synchronics offers on-site emergency repair and loaner equipment options to minimize generator downtime.
What warranty do you offer on Ansaldo repairs and does Synchronics provide spare parts?+
Synchronics provides 6-month comprehensive warranty on all labor and replaced components. We maintain stocks of critical Ansaldo spare parts including thyristor modules, capacitor banks, solenoid coils, and printed circuit board assemblies. For obsolete Ansaldo parts from 1990s-2000s power plants, we perform component reverse-engineering and circuit-compatible sourcing. Field failure analysis and root-cause reporting is provided for all major repairs to help prevent recurrence.
How do I send my ANSALDO unit for repair?+

What is the cost of repairing a ANSALDO 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 ANSALDO 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 ANSALDO 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.
