AVG Equipment We Repair — By Category
AVG Product Lines We Repair
Our engineers are trained on the full AVG product range. Below are the major product families we service.
AVG Surge Protective Devices (SPDs)
Modular and plug-in surge arresters protecting LV and MV circuits. Common faults: thermal disconnect failures, clogged pressure relief valves, varistor degradation under repeated transient stress. Industrial environments with frequent switching and lightning-prone regions report highest failure rates.
AVG Electrical Distribution Boards
Compact modular switchgear for industrial control centres. Failures stem from moisture ingress, loose terminal connections under vibration, and contact wear on switching mechanisms. Common in textile mills and automotive assembly plants operating in humid regions.
AVG Lightning Protection Systems
Integrated earthing and lightning conductor solutions for industrial structures. Typical issues: corrosion of copper conductors, faulty equipotential bonding connections, and SPD coordination failures during multi-strike events.
AVG Transient Voltage Suppressors
Solid-state protection for control circuits and sensor lines. Degradation occurs from cumulative energy absorption, thermal cycling in manufacturing floors, and inadequate ventilation in control panels. Replacement required when suppression voltage drifts beyond tolerance.
AVG Residual Current Protection
RCD and differential switching devices for personnel and equipment safety. Faults include sluggish trip response, false tripping from harmonic distortion, and worn solenoid coils. Critical in food processing, textile, and chemical plants with high fault current exposure.

Common AVG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AVG equipment arriving at our workshop.
- ✓SPD varistor degradation under transient stress — Repeated lightning strikes or switching transients cause metal oxide varistor (MOV) internal junction temperature rise, leading to resistance drift and reduced suppression capability. High-humidity industrial zones in Gujarat, Maharashtra, and coastal Tamil Nadu experience accelerated failure due to moisture and thermal cycling.
- ✓Thermal disconnect malfunction in surge arresters — AVG SPDs include thermal disconnect (TD) mechanisms that isolate failed MOVs to prevent fire hazard. Contacts stick when exposed to dust, mineral oils from nearby transformers, or inadequate panel ventilation—preventing automatic isolation during thermal runaway.
- ✓Loose terminal connections causing voltage drop and arcing — AVG distribution boards and SPD mounting rails experience vibration from adjacent machinery—especially common in textile mills, paper plants, and food processing facilities. Copper-to-aluminum contact oxidation at terminals accelerates loosening and creates intermittent arcing faults that damage switching elements.
- ✓Moisture ingress causing tracking and short circuits — Coastal, humid, and monsoon-affected regions allow condensation to accumulate inside AVG switchboards, especially if ventilation holes are blocked by dust or debris. Tracking initiates between closely-spaced contacts on distribution boards, leading to phase-to-earth faults and nuisance tripping.
- ✓RCD trip delay or failure to trip on fault current — AVG time-delayed RCDs used in motor control circuits may lose sensitivity due to solenoid coil wear, permanent magnet weakening, or harmonic distortion in VFD-driven systems (common in cement and steel mills). Calibration drift causes nuisance tripping or no-trip conditions.
- ✓Equipotential bonding failure in lightning protection system — AVG external lightning conductors and internal bonding straps corrode or loosen over 10+ years in industrial coastal zones. Corrosion of copper straps reduces conductivity; loose clamps fail to maintain bonding continuity between structure frames and SPD earth points. Results in potential differences during lightning strikes that damage control circuits.

Frequently Asked Questions — AVG Repairs
Do you repair AVG equipment anywhere in India?+
Yes. Synchronics repairs the complete AVG product range—surge protective devices, distribution boards, lightning protection systems, and residual current devices. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other cities. All repairs are processed at our 20,000 sq ft facility in Vadodara, Gujarat, with 48–72 hour turnaround for most SPD and board faults.
What is the difference between AVG Type 2 and Type 3 SPDs, and which should I repair vs. replace?+
AVG Type 2 SPDs protect against induced surges from internal switching and nearby lightning (installed on incoming distribution boards). Type 3 units protect individual circuits and control lines from residual surges. Type 2 devices are repairable—Synchronics replaces varistors, thermal disconnects, and test connections. Type 3 modular cartridges are usually cost-effective to replace if varistors are degraded. We advise based on cartridge age, strike history, and remaining suppression margin after load testing.
How do I know if my AVG surge arrester needs repair or replacement?+
Synchronics performs residual voltage testing, insulation resistance measurement, and thermal imaging of your AVG SPD. If varistor degradation is <15% and no signs of thermal runaway or moisture damage exist, we repair (replace cartridge and re-validate). If resistance has drifted >20% or thermal disconnect has failed, replacement is recommended for safety compliance. We provide written test reports with voltage-current curves for your maintenance records.
Can Synchronics repair AVG RCDs that false-trip due to VFD harmonics?+
Yes. Synchronics offers selective time-delayed AVG RCD upgrades specifically designed for VFD and motor drive environments. We also retrofit harmonic filters and recommend three-phase RCDs with 30 mA selectivity rated for >100 kHz transient immunity. Before upgrade, we test your current RCD threshold under actual plant VFD load to confirm harmonic contribution. This is common in textile mills, cement kilns, and automotive paint lines.
Do you supply genuine AVG spare parts or refurbished modules?+
Synchronics stocks genuine AVG cartridges, thermal disconnects, solenoid coils, and contact assemblies sourced through authorized Indian distributors. For cost-sensitive repairs of older boards (5+ years), we offer refurbished components tested to full OEM specification and backed by 12-month warranty. All work includes supply of spare parts, labour, testing, and professional documentation.
How do I send my AVG 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 AVG 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 AVG 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 AVG 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.
