GENCO Product Lines We Repair
Our engineers are trained on the full GENCO product range. Below are the major product families we service.
GENCO AVR (Automatic Voltage Regulators)
GENCO AVRs maintain constant generator output voltage under varying load conditions. Common failures include capacitor degradation, sensing circuit faults, and thyristor bridge failures. Synchronics diagnoses voltage instability, oscillation, and reference loss issues.
GENCO Load Control Modules
Load sharing and parallel generator synchronization units for multi-unit installations. Typical faults include CT ratio errors, phase angle drift, and load imbalance logic failures affecting industrial power distribution systems.
GENCO Excitation Control Systems
Brush and brushless exciter control boards managing field current to generator rotors. Repair focus includes gate driver PCB failures, IGBT shortages, and field loss detection module malfunctions in cement, steel, and mining operations.
GENCO Synchronization Panels
Synchroscope and paralleling relay modules for safe generator connection to grid or other units. Common issues include synchronizing relay drift, frequency sensing errors, and phase angle measurement failures affecting power plant operations.
GENCO Generator Protection Relays
Multi-function protection units detecting over-voltage, under-voltage, over-frequency, loss of synchronization, and reverse power faults. Typical repairs involve analog input card calibration, relay contact wear, and firmware updates on microprocessor-based units.
GENCO Control Cabinets and Panels
Integrated generator control houses combining AVR, sync relay, and protection in single enclosure. Repair scope includes terminal block corrosion, wiring harness degradation, internal cooling fan failures, and PLC module reprogramming for Indian industrial climates.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common GENCO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GENCO equipment arriving at our workshop.
- ✓Voltage regulation unstable or drifting continuously — GENCO AVR reference voltage divider network degradation, faulty sensing transformer, or capacitor leakage in the control circuit. Common in humid Indian industrial environments and high-temperature engine rooms.
- ✓Generator paralleling fails or synchronization relay chatters — GENCO synchroscope sensing error, phase angle drift, or frequency detection module calibration loss. Often caused by CT wiring faults or core saturation in transducers exposed to monsoon moisture ingress.
- ✓Load sharing unequal between parallel generators — GENCO load control module droop network imbalance, CT ratio mismatch, or current transducer offset drift. Particularly common in multi-unit textile mills and data centres with varying power ratings.
- ✓Generator field loss detection triggered incorrectly — GENCO excitation control sensing circuit noise, threshold misalignment, or broken feedback wiring from rotor slip rings. Fouled signal integrity from nearby power electronics or motor soft starters.
- ✓Over-voltage or over-frequency protection relay intermittent — GENCO protection relay analog input card calibration drift, faulty pressure spring contact in relay armature, or firmware corruption in microprocessor-based units after power transients.
- ✓Control cabinet cooling fan not running or noisy bearing — GENCO cabinet thermal management failure due to dust accumulation in humid Indian mills, motor bearing seizure, or faulty temperature sensor triggering false shutdown. Enclosure gasket degradation allows moisture entry.

We offer PAN-India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all tier-2 cities. Our main repair facility is in Vadodara, Gujarat. Most repairs completed within 5-7 working days.
What is the typical repair cost for GENCO AVR or load control module failure?+
GENCO AVR repair typically costs Rs. 8,000-15,000 depending on component damage scope (capacitors, thyristors, sensing circuits). Load control modules range Rs. 12,000-22,000 for recalibration and card replacement. Synchronics provides free diagnostic report and repair quote within 24 hours of equipment receipt. We use OEM-equivalent parts and offer 12-month warranty on all repairs.

Yes. Our engineers have reverse-engineered and repaired hundreds of GENCO installations across Indian industrial plants. We maintain comprehensive technical libraries for GENCO AVR, sync relay, and protection module schematics and calibration procedures. Even damaged or unmarked PCBs can be identified and repaired through functional testing and cross-reference matching against our database.
Does Synchronics offer on-site GENCO generator control troubleshooting and commissioning?+
Yes. Synchronics offers on-site diagnostic visits for GENCO installations in Maharashtra, Gujarat, Madhya Pradesh, Rajasthan, and adjacent regions. Our field engineers can perform voltage regulation tuning, synchronization relay calibration, and load-sharing verification at your plant with portable test equipment. Emergency breakdown support and weekend callout available for critical power backup systems.
What is the warranty and turnaround time for GENCO repairs at Synchronics?+
Standard repair turnaround is 5-7 working days for AVR, load control, and protection relay units. Express turnaround (2-3 days) available for critical installations at 20% premium. All repairs carry 12-month parts and labour warranty with free return courier. We provide detailed test reports showing voltage regulation accuracy, frequency response, and protection relay timing — essential for compliance audits at power plants and industrial facilities.
How do I send my GENCO unit for repair?+

What is the cost of repairing a GENCO 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 GENCO 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 GENCO 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.
