GRESHAM POWER Product Lines We Repair
Our engineers are trained on the full GRESHAM POWER product range. Below are the major product families we service.
Gresham Alternators and Generators
AC synchronous alternators and generator sets ranging from 100 kVA to several MVA. Common faults include bearing wear, winding insulation breakdown, and rotor excitation failures. Synchronics provides rewinding, bearing replacement, and full load testing.
Gresham Governor and Load Control Systems
Mechanical and electronic governor units for engine-driven and turbine-driven power generation. Issues include hunting oscillations, droop calibration drift, and actuator sticking. Synchronics specialises in governor tuning and actuator restoration.
Gresham Electrical Protection Relays
Static and electromechanical protective relays for generator backup and distribution circuits. Common failures: setting drift, contact pitting, and calibration loss. Synchronics recalibrates and restores relay functionality to specification.
Gresham Excitation and Voltage Regulation Systems
Brush and brushless exciter units with automatic voltage regulation (AVR) circuits. Failure modes include AVR amplifier faults, exciter winding short circuits, and brush wear in older models. Full electronic and mechanical reconditioning available.
Gresham Synchronisation and Switchgear Control
Synchroscope, synchroniser modules, and automatic circuit breaker control equipment for generator paralleling and grid connection. Defects include phase-sensitive relay drift, time-delay capacitor failures, and logic card oxidation.
Gresham Power Quality and Metering Systems
Harmonic analysers, power factor correction units, and multi-function metering terminals. Repairs cover software reloading, sensor recalibration, and display module replacement.

Common GRESHAM POWER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GRESHAM POWER equipment arriving at our workshop.
- ✓Alternator output voltage fluctuation and collapse — Exciter winding short-circuit or brush collection ring carbon buildup in Gresham brushless exciters. Aged rotating exciters suffer brush wear leading to intermittent excitation current. AVR capacitor degradation in static systems causes unstable voltage regulation.
- ✓Governor hunting and speed instability — Mechanical governor linkage friction, worn actuator seals, or droop adjustment misalignment in Gresham governor assemblies. Electronic load governors suffer from PID tuning drift after years of operation, causing load oscillation between 5-15% of rated speed.
- ✓Protection relay setting drift and non-operation — Gresham electromechanical relays suffer thermal drift in setting springs and moving contact gaps. Static relays experience capacitor leakage, transistor degradation, and circuit board oxidation in high-humidity Indian environments. Calibration shifts render relays ineffective at fault detection.
- ✓Bearing failure and mechanical noise from generator — Gresham alternator and generator bearing wear due to misalignment, lubrication degradation, or shaft imbalance. Long operational hours cause radial and thrust bearing races to develop spalling and increased clearance, producing audible grinding or howling during load.
- ✓Winding insulation breakdown and phase-to-ground faults — Alternator and generator stator winding insulation degradation caused by thermal cycling, vibration, moisture ingress, and age. Gresham machines in coastal or humid industrial zones experience accelerated insulation failure. Voltage surges from lightning or switching transients can initiate winding faults.
- ✓Synchroniser and paralleling control failure — Gresham synchroscope and electronic synchroniser units fail due to phase-sensitive relay contact wear, capacitor leakage in delay circuits, and logic card corrosion. Electromechanical models suffer from moving-coil damping fluid degradation and pointer sticking.

Frequently Asked Questions — GRESHAM POWER Repairs
Do you repair Gresham Power equipment anywhere in India?+
Yes, absolutely. Synchronics repairs the full Gresham Power product range including alternators, generators, governors, protection relays, exciters, and synchronisation equipment. We offer PAN India door pickup and delivery from major cities including Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Surat, and all other industrial centres. All repairs are completed in our 8000 sqft facility in Vadodara, Gujarat, with no outsourcing.
What is the typical turnaround time for a Gresham Power alternator repair?+
Turnaround depends on fault severity. Routine bearing or brush replacement typically takes 5-7 working days. Stator winding rewind requires 15-21 days including moisture cure and testing. We offer expedited service for power utilities and large industrial clients. Emergency onsite diagnostics are available for generator failures impacting production.
Can you repair legacy Gresham Power mechanical governors and synchronisers?+
Yes. Synchronics specialises in restoring Gresham heritage mechanical governor units and electromechanical synchroscopes dating back to the 1950s-1980s. Our engineers understand Gresham linkage design, droop calibration, and dashpot tuning. We source or manufacture replacement components including actuator seals, spring sets, and moving contacts. Full functional testing ensures restored equipment matches original performance.
How do you handle Gresham Power protection relay recalibration?+
Synchronics uses calibrated Megohmmeter and relay test sets to measure actual pickup currents and time delays on every Gresham overcurrent, earth fault, and differential relay. If readings drift from nameplate specification, we adjust moving contacts, replace springs, and recalibrate setting discs to restore original operating curves. All relays receive INSL 81 compliance certification post-repair.
Do you provide warranty on Gresham Power repairs?+
Yes. All repairs carry a 12-month comprehensive warranty covering parts and labour. If a repaired unit fails due to our workmanship, we repair or replace it free of charge. High-value alternators and generators can opt for extended 24-month warranty. Warranty is void only if equipment is operated outside Gresham specification or subjected to unauthorised modification.
How do I send my GRESHAM POWER 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 GRESHAM POWER 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 GRESHAM POWER 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 GRESHAM POWER 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.
