CG Product Lines We Repair
Our engineers are trained on the full CG product range. Below are the major product families we service.
CG Switchgear Range (HT/LT)
CG's High Tension and Low Tension switchboards, circuit breakers, and isolators used in substations and industrial distribution. Common issues include contact erosion, trip mechanism failure, and insulation breakdown in 11kV and 33kV applications.
CG Distribution Transformers
Oil-immersed and dry-type transformers from 100kVA to 10MVA for industrial substations. Repair focuses on core insulation recovery, winding resistance correction, and oil quality restoration in Indian heat and dust conditions.
CG Power Capacitor Banks
Medium and High Voltage capacitor units for power factor correction in industrial plants. Failures include dielectric breakdown, fuse element degradation, and internal arcing from voltage transients common in Indian grid.
CG Control and Metering Panels
Integrated electrical control cabinets, PLC enclosures, and energy metering systems for factory automation. Common faults include relay coil burn-out, contactor wear, and circuit card degradation from moisture and industrial vibration.
CG Relay and Protection Systems
Electromagnetic and static relays, protection modules for transformer and feeder protection. Issues stem from coil insulation failure, moving contact misalignment, and calibration drift in Indian thermal environments.

Common CG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CG equipment arriving at our workshop.
- ✓CG VCB Contact Erosion and Trip Failure — High-current interruption in 11kV/33kV switchgear causes silver-alloy contact faces to erode, reducing contact pressure and preventing reliable arc extinction. Moisture ingress in Indian coastal and humid regions accelerates oxidation and contact sticking.
- ✓CG Distribution Transformer Winding Insulation Breakdown — Moisture absorption into cellulose insulation and transformer oil, combined with thermal cycling in Indian summer heat (50°C+), weakens dielectric strength. Acid formation in aged oil accelerates paper degradation and core hotspot creeping.
- ✓CG APFC Capacitor Unit Bank Dielectric Failure — Voltage transients from grid switching, harmonic distortion from non-linear loads in Indian manufacturing, and internal thermal stress cause capacitor film breakdown. Fuse element failure leaves failed units in circuit, escalating voltage stress on healthy capacitors.
- ✓CG Control Panel Relay Coil Burn-Out and Chatter — Continuous inrush current during frequent motor starts, suppressed-voltage switching spikes, and inadequate snubbing across relay coil terminals cause insulation carbonization. Dust and humidity in Indian factory floors promote surface leakage paths leading to partial short circuits.
- ✓CG Energy Meter Display Malfunction and Data Loss — Electromagnetic interference (EMI) from nearby switching stations, power quality disturbances, and internal battery degradation cause micro-controller reset and memory corruption. Poorly shielded meter cabinets in Indian substations compound EMI susceptibility.
- ✓CG Motor Starter ACB Contact Resistance Increase and Overheating — Repeated high-current switching (100+ A), corrosion of moving and stationary contacts in humid/saline environments, and inadequate contact wiping force lead to resistive heating and slow motor acceleration. Contact gap misalignment accumulates over years of use in Indian textile and sugar industries.

Frequently Asked Questions — CG Repairs
Do you repair CG equipment anywhere in India?+
Yes. Synchronics repairs the complete CG product range — switchgear, transformers, capacitor banks, control panels, relays, and metering systems. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other major industrial cities. Repairs are completed at our ISO-certified facility in Vadodara, Gujarat, with turn-around time of 5-15 working days depending on fault complexity.
What is the typical repair cost for a CG 11kV Vacuum Circuit Breaker?+
11kV VCB repair at Synchronics ranges from Rs. 15,000 to Rs. 35,000 depending on the extent of contact erosion, mechanism wear, and whether the vacuum bottle requires replacement. We provide detailed quotation after fault diagnosis. Many industrial plants find repair economical compared to OEM replacement costing Rs. 2.5-4 lakhs. We also offer warranty on repaired VCB performance.
Can you recondition CG distribution transformers that have failed dielectric strength tests?+
Yes, absolutely. Synchronics specializes in transformer oil reclamation and winding re-impregnation for failed CG transformers. We use vacuum hot-oil circulation drying (achieving moisture content <10ppm), acid-removing oil treatment, and controlled re-impregnation. Success rate exceeds 85% for transformers with insulation power factor >20% before treatment. We conduct final hi-pot, oil analysis, and no-load/load testing before dispatch to your site.
Do you provide genuine CG spare parts as part of repair work?+
Yes. Synchronics maintains stock of genuine CG replacement components including contacts, coils, capacitor units, relays, fuses, and control circuit cards. We do not substitute with third-party parts unless explicitly approved by you in writing. All parts carry CG original warranty and are certified for compatibility with your specific equipment model and vintage. Parts cost is itemized separately in repair invoices.
What testing standards does Synchronics follow for CG switchgear after repair?+
Post-repair testing includes mechanical operation cycle count, high-voltage trip function verification, contact resistance measurement (<0.5 milliohm), insulation integrity check (>10 Megohm at 2.5kV), oil/gas tightness verification, and thermal imaging under full current load. For critical equipment serving power utilities, we perform additional routine maintenance tests (RMT) per IS/IEC standards and provide certified test reports. Your plant's acceptance criteria are also incorporated into the test protocol.
How do I send my CG 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 CG 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 CG 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 CG 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.
