ELTEX OF SWEDEN AB Equipment We Repair — By Category
ELTEX OF SWEDEN AB Product Lines We Repair
Our engineers are trained on the full ELTEX OF SWEDEN AB product range. Below are the major product families we service.
ELTEX Voltage Regulators
Automatic voltage regulation units for maintaining stable supply to sensitive industrial loads. Common faults include thyristor stack failure, control circuit malfunction, and response lag under transient conditions. Synchronics performs thyristor replacement, output transformer testing, and firmware recalibration.
ELTEX High-Voltage Switchgear
Vacuum and SF6-insulated disconnect switches rated 6.6kV to 33kV for industrial substations. Repair challenges include contact erosion, mechanism jamming, and arc-quenching gas purity loss. Synchronics offers contact replacement, mechanism overhaul, and gas analysis services.
ELTEX Control Relay Modules
Solid-state and electromagnetic relay modules for motor protection, feeder control, and fault signaling in industrial panels. Typical issues include optocoupler degradation, timing capacitor failure, and coil insulation breakdown. Synchronics tests relays under load and replaces defective modules with matching specifications.
ELTEX Disconnect and Earthing Switches
Manual and motor-operated disconnect switches with integrated earthing blades for safe equipment isolation. Failure modes include blade misalignment, interlocking mechanism wear, and spring fatigue. Synchronics performs blade re-racking, interlock servicing, and mechanical re-testing.
ELTEX Surge Arresters
Metal oxide and gapless surge protection devices for distribution and transmission lines. Common defects include porcelain cracking, leakage current elevation, and internal element deterioration. Synchronics replaces arresters, performs leakage current measurement, and advises on equipment grounding.
ELTEX Metering and Instrumentation Transformers
Current and voltage transformers for revenue metering and protective relaying in substations. Repair needs include core saturation, winding insulation testing, and secondary circuit restoration. Synchronics offers transformer oil analysis, winding resistance measurement, and sealing restoration.

Common ELTEX OF SWEDEN AB Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELTEX OF SWEDEN AB equipment arriving at our workshop.
- ✓AVR thyristor stack short circuit — Repeated over-voltage transients or aging thyristor die degradation in ELTEX voltage regulators cause junction leakage and eventual short. This is common in plants with weak grid conditions or frequent motor starting loads.
- ✓Switchgear contact welding under fault current — High fault currents or inadequate contact pressure in ELTEX high-voltage switches cause contact surfaces to fuse together, preventing normal disconnection. Contamination and arcing contribute to welding.
- ✓Control relay coil insulation breakdown — Moisture ingress, thermal cycling, and age-related degradation of paper and enamel insulation in ELTEX relay coils reduce isolation resistance to ground, causing coil shorts and relay malfunction.
- ✓Disconnect switch blade misalignment and drag — Mechanical wear in blade guides, inadequate lubrication, and corrosion of internal mechanisms in ELTEX disconnect switches cause high insertion and extraction force, risking blade jamming during emergency switching.
- ✓Surge arrester leakage current increase above threshold — Moisture diffusion into metal oxide discs, thermal aging, and contaminant absorption in ELTEX arresters cause leakage current to rise gradually, signaling imminent breakdown risk.
- ✓Current transformer core saturation and secondary overvoltage — Excessive primary current, burden mismatch, or core material degradation in ELTEX metering CTs causes core saturation, producing dangerously high secondary voltages that damage instruments and relays.

Frequently Asked Questions — ELTEX OF SWEDEN AB Repairs
Do you repair ELTEX of Sweden AB equipment anywhere in India?+
Yes. Synchronics repairs the full ELTEX of Sweden AB product range — voltage regulators, high-voltage switchgear, control relay modules, disconnect switches, surge arresters, and metering transformers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, and all other major cities. All repairs are performed at our facility in Vadodara, Gujarat, with 3-10 day turnaround depending on complexity.
What is the typical repair cost for an ELTEX voltage regulator failure?+
ELTEX AVR repair costs depend on failure severity. Thyristor stack replacement typically runs Rs. 15,000–40,000; control circuit repairs Rs. 8,000–20,000. Synchronics provides free diagnostic testing and a detailed quote before work begins. We source genuine ELTEX spares, ensuring long-term reliability and protection of your investment.
How do I know if my ELTEX switchgear contacts need replacement?+
Signs include visible pitting or erosion on contact faces, increased insertion force, arcing during switching, or temperature rise at the switch terminal. Synchronics offers on-site inspection and contact resistance measurement using a micro-ohmmeter. We recommend preventive contact replacement every 5–8 years in high-load applications or after 10,000+ operating cycles.
Can Synchronics repair ELTEX control relays or must they be replaced?+
Synchronics can repair older ELTEX relay modules if components are available — such as replacing optocouplers, capacitors, or coils. However, solid-state relays often require full replacement due to component obsolescence. We assess repair viability during diagnostic testing and always recommend the most cost-effective path forward, whether repair or replacement.
What spares does Synchronics stock for ELTEX equipment?+
Synchronics maintains critical spare stock for ELTEX products including thyristor pairs, relay modules, contact sets, surge arrester elements, and transformer oils. For rare or specialized components, we can source directly from ELTEX distributors in Europe or India. Lead times for special orders are typically 2–4 weeks.
How do I send my ELTEX OF SWEDEN AB 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 ELTEX OF SWEDEN AB 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 ELTEX OF SWEDEN AB 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 ELTEX OF SWEDEN AB 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.
