ASEA Product Lines We Repair
Our engineers are trained on the full ASEA product range. Below are the major product families we service.
ASEA High-Voltage Switchgear
Oil-immersed and vacuum circuit breakers used in power transmission and industrial substations. Common faults include insulation degradation, SF6 gas leakage, and mechanical latch failures requiring specialist high-voltage testing.
ASEA Thyristor Control Modules
Silicon-controlled rectifier modules for DC motor drives and industrial power conversion. Prone to gate drive failures, snubber capacitor degradation, and commutation circuit faults in harsh mill environments.
ASEA Synchronous Motor Controllers
Excitation and field control systems for large synchronous motors in cement and steel plants. Susceptible to voltage regulator drift, rectifier diode failure, and brush wear in slip-ring assemblies.
ASEA Industrial Automation Modules
Relay logic modules and early PLC components for plant automation. Aging modules suffer from contact oxidation, capacitor leakage, and relay coil burnout after decades of operation.
ASEA Power Transformers
Oil-cooled power transformers for industrial substations and heavy manufacturing. Prone to winding insulation breakdown, tap changer contact wear, and cooling system failures in tropical Indian climates.
ASEA DC Drive Systems
Variable-speed DC motor control systems for rolling mills, paper plants, and textile machinery. Faults include armature feedback sensor malfunction, commutation circuit instability, and power stage thermal runaway.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common ASEA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ASEA equipment arriving at our workshop.
- ✓Thyristor gate drive circuit failure — Aging optocoupler modules and transformer saturation in ASEA THYRITEC units cause loss of gate pulse signal, preventing thyristor firing in DC drives. Dust and moisture ingress accelerate component degradation in Indian plant environments.
- ✓Excitation voltage regulator drift on UNITROL systems — Aging potentiometers and reference voltage drift in ASEA UNITROL field controllers cause synchronous motors to drop load or lose synchronism. Temperature fluctuations in hot Indian mills worsen capacitor tolerance drift.
- ✓Slip-ring and brush wear causing field current ripple — ASEA brushless excitation systems suffer brush dust accumulation and slip-ring corrosion in humid Indian climates, increasing brush contact resistance and inducing harmonic ripple in DC field current.
- ✓Capacitor leakage in snubber and commutation circuits — Electrolytic capacitors in ASEA thyristor snubber networks and commutation circuits degrade due to thermal cycling in high-ambient-temperature mills, causing capacitor ESR increase and commutation circuit malfunction.
- ✓Oil insulation breakdown in high-voltage switchgear — ASEA HGIS and vacuum breaker oil becomes contaminated by moisture and particulates in tropical India warehouses, reducing dielectric strength and risking internal arcing during high-voltage transients.
- ✓Cooling fan motor failure on power transformer controllers — ASEA power transformer cooling systems experience pump motor burnout due to dust-choked cooling fins and thermal overload in Indian steel and cement plants, especially during summer peak loads.

Frequently Asked Questions — ASEA Repairs
Does Synchronics repair ASEA equipment throughout India?+
Yes. Synchronics offers pan-India repair service for all ASEA industrial electronics including switchgear, thyristor drives, excitation controllers, and automation modules. We provide door pickup and delivery from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other Indian cities. Our primary repair facility is in Vadodara, Gujarat, with a fast turnaround guarantee.
What ASEA products does Synchronics specialize in repairing?+
Synchronics repairs the complete ASEA industrial electronics range: high-voltage switchgear (HGIS, MEGAPULS), thyristor and converter modules (THYRITEC, STAVAC), synchronous motor excitation controllers (UNITROL), automation relay modules (ACIA), and DC drive systems. We also service ASEA power transformer cooling systems and control electronics. Our engineers hold extensive factory training on ASEA legacy and modern equipment.
How long does ASEA equipment repair typically take at Synchronics?+
Standard ASEA repairs average 7-10 working days depending on fault complexity and component availability. Thyristor gate drive and excitation controller faults usually resolve in 5-7 days. High-voltage switchgear testing and oil reclamation may take 10-14 days. We offer expedited repair for critical plant shutdown situations. All timelines include full FAT (factory acceptance test) and documentation.
Does Synchronics stock genuine ASEA spare parts?+
Synchronics maintains inventory of critical ASEA spare components including optocouplers, power rectifier diodes, excitation capacitors, and control relay modules. For obsolete ASEA components (e.g., legacy ACIA modules), we source cross-compatible industrial-grade replacements and validate functional equivalence before installation. Genuine ASEA component sourcing is also available with extended lead time.
Can Synchronics repair ASEA equipment that has been idle for years in Indian plants?+
Yes. Our technicians specialize in recommissioning dormant ASEA industrial systems. We perform comprehensive insulation testing, capacitor reformation, oil dielectric breakdown analysis, and full functional verification before return to service. Synchronics has successfully restored decades-old ASEA switchgear and drive systems in Indian steel mills and refineries, extending equipment life by 10+ years.
How do I send my ASEA 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 ASEA 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 ASEA 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 ASEA 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.
