Expert restoration of legacy and modern GEC industrial electrical equipment across India.
GEC Product Lines We Repair
Our engineers are trained on the full GEC product range. Below are the major product families we service.
GEC Protection Relays & Switchgear
GEC's range of electromechanical and static protection relays (MCGG, PEKD, SZGE, RRCA types) and vacuum/air-break switchgear. Common issues include worn contact surfaces, relay calibration drift, and obsolete spare part sourcing for 20-40 year old units.
GEC Alsthom AC Drives & Frequency Converters
Industrial AC drive units for motor speed control in textiles, cement, and pulp-paper mills. Faults include thyristor/IGBT gate drive failures, DC bus capacitor aging, and firmware corruption in older digital control boards.
GEC Motor Starters & Soft Starters
Star-delta and solid-state soft-start controllers for pump, fan, and compressor motors. Wear in mechanical contactors, thermal overload relay calibration loss, and power electronic component degradation are frequent failure modes.
GEC Control & Automation Panels
Custom-built electrical distribution and automation enclosures for Indian textile mills, sugar factories, and power plants. Repair challenges include aging wiring insulation, corroded terminal blocks, and obsolete contactor replacements in humid coastal environments.
GEC Transformer Protection Systems
Buchholz relays, oil-immersed fault detection, and temperature monitoring systems for power transformers in substations and industrial sites. Common faults: sensor drift, oil contamination effects on relay response, and mechanical float/mercury switch stiction.

Common GEC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GEC equipment arriving at our workshop.
- ✓GEC Protection Relay Calibration Drift — Sensitivity Loss — Electromechanical relay coils in GEC MCGG, PEKD, and RRCA series experience winding insulation degradation and core saturation shifts after 20-30 years of operation, causing threshold voltage/current settings to creep out of specification.
- ✓GEC Alsthom Drive Thyristor Gate Drive Failure — No Output Power — Power electronic thyristor or IGBT gate drive circuits in GEC Alsthom ACS-160/280 series fail due to capacitor dry-out in the gate power supply, solder joint fatigue on gate transformer leads, or optical isolation coupler degradation from heat cycling.
- ✓GEC Contactor Contact Welding — Seized Mechanical Contact Set — Inrush current spikes, arc erosion buildup on silver-alloy contacts, and inadequate arc suppression in GEC C160 and soft-starter contactors cause silvering bridges to form between contacts, making manual or electrical release impossible.
- ✓GEC AC Drive DC Bus Capacitor Failure — Loud Hum, Voltage Instability — Aluminum electrolytic DC bus capacitors (typically 2200-4700µF at 500-700V) in GEC Alsthom drives age in high-ambient-temperature enclosures (common in Indian summer), causing ESR rise, capacitance loss, and eventual bulging or leaking.
- ✓GEC Buchholz Relay Float Stiction — No Trip on Oil Surge — The mechanical float and mercury switch assembly in GEC Buchholz BGV-2 relays accumulates fine sludge and oxidized oil particles, reducing float buoyancy and slowing mercury column response during transformer oil surges.
- ✓GEC Soft Starter IGBT Module Thermal Runaway — Shutdown During Load — Thermal interface material between IGBT module and heatsink degrades over 10-15 years, reducing heat transfer and causing localized junction temperature rise. Positive temperature coefficient of IGBT Vce(sat) drives more current, accelerating thermal runaway and triggering overheat shutdown.

Frequently Asked Questions — GEC Repairs
Do you repair GEC equipment anywhere in India?+
Yes. Synchronics repairs the full GEC product range — protection relays, switchgear, AC drives, soft starters, motor controllers, and automation panels. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, Indore, and all other cities. All equipment is repaired in our ISO-certified facility in Vadodara, Gujarat.
I have a GEC protection relay from 1998. Can you still repair it, or must I replace it?+
We repair GEC relays from the 1980s onward. Electromechanical relays like the MCGG, PEKD, RRCA, and SZGE series are fully restorable. Synchronics recalibrates coils, cleans and resurfaces contacts, and supplies upgrade kits (solid-state modules, modern arc suppressors) if you wish to extend life. Most Indian sugar mills and textile mills run GEC relays we repaired 15+ years ago.
What is your turnaround time for GEC Alsthom AC drive repair?+
Standard GEC drive repair (board swap, capacitor replacement, thyristor testing) takes 5-7 working days after receipt. Complex issues (firmware recovery, custom gate drive redesign) take 10-14 days. We ship repaired drives with 12-month workmanship warranty. Express turnaround (2-3 days) is available for critical plant shutdowns in India.
Do you have spare parts for discontinued GEC products?+
Synchronics maintains an inventory of obsolete GEC contactor coils, relay springs, capacitor modules, thyristors, and control circuit boards. For items not in stock, we source from UK and European suppliers with whom we have established relationships. We can also design and manufacture functional substitutes (e.g., solid-state relay upgrades for mechanical contactors) if original parts are unavailable.
Is your GEC repair service compliant with Indian electrical codes and safety standards?+
All our GEC repairs are carried out per IS:2705 (Protection Relays), IS:6220 (Transformer Protection), IS:13595 (Power Electronics), and IEC standards applicable in India. We issue calibration certificates, test reports, and performance graphs with every repair. Our Vadodara facility holds ISO 9001:2015 and ISO 14001 certifications.
How do I send my GEC 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 GEC 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 GEC 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 GEC 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.
