FACTS Product Lines We Repair
Our engineers are trained on the full FACTS product range. Below are the major product families we service.
STATCOM Controllers
Static Synchronous Compensator control systems managing reactive power and voltage support in transmission networks. Common issues include thyristor firing circuit failures, capacitor bank faults, and gate driver malfunctions affecting grid stability.
SVC (Static Var Compensator) Systems
Thyristor-controlled reactor and capacitor banks for dynamic reactive power compensation. Typical repair needs involve thyristor stack failures, coupling transformer issues, and harmonic filter degradation in high-MVAr applications.
UPFC (Unified Power Flow Controller)
Series-shunt converter systems enabling real-time power flow control across transmission corridors. Common faults include DC link capacitor aging, PWM gate drive failures, and control algorithm processor resets.
Gate Drive and Trigger Units
High-reliability thyristor and IGBT gate drive circuits handling 6-12 kV pulse signals. Frequent failures stem from optical isolation breakdown, pulse transformer saturation, and gate capacitor degradation under thermal cycling.
Power Quality Monitoring Devices
Real-time harmonic and transient analyzers integrated with FACTS systems for grid stability assessment. Issues include analog input module failures, signal conditioning circuit drift, and firmware corruption.

Common FACTS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FACTS equipment arriving at our workshop.
- ✓Thyristor Stack Thermal Runaway — Degraded junction temperature sensors or cooling system blockage in thyristor valve blocks causes uncontrolled current rise. This is critical in SVCs and STATCOMs during high reactive power demand periods typical in Indian monsoon seasons affecting transmission stability.
- ✓Gate Drive Optical Isolation Failure — High-voltage transients and EMI from switching events degrade optocoupler LEDs in gate drive units. This leads to loss of firing pulses, causing converter dropout and grid voltage instability in STATCOM and UPFC applications.
- ✓DC Link Capacitor Bank Failure — Aluminum electrolytic capacitors in UPFC and STATCOM DC links age under continuous ripple current and elevated junction temperatures (50-60°C typical in Indian summer). Electrolyte evaporation leads to ESR rise and capacitor venting.
- ✓Control Processor Reset and Watchdog Timeout — Power supply voltage sag during grid transients, ground loops in multi-level control systems, or corrupted firmware in STATCOM and UPFC controllers trigger processor resets. Loss of control synchronization causes rapid power swings and grid instability.
- ✓Coupling and Output Transformer Core Saturation — DC bias from unbalanced thyristor firing or residual magnetism in transformer cores causes core saturation in SVC and UPFC output circuits. Harmonic distortion rises sharply, affecting THD compliance and neighboring utility equipment.
- ✓Harmonic Filter Capacitor Bank Resonance — Capacitor aging and inductance mismatch in series harmonic filters create inadvertent resonance peaks at 3rd, 5th, or 7th harmonic frequencies. This amplifies harmonic currents, tripping overcurrent relays and destabilizing FACTS performance.

Frequently Asked Questions — FACTS Repairs
Do you repair FACTS equipment anywhere in India?+
Yes. Synchronics repairs the full range of FACTS systems — STATCOMs, SVCs, UPFCs, thyristor gate drives, and power quality monitoring modules across India. We offer PAN India door pickup and courier from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, Kolkata, and all other metros. All repairs are handled at our Vadodara, Gujarat facility with 180+ specialized engineers.
How do you handle FACTS control algorithm and firmware faults?+
FACTS controllers often fail due to corrupted control firmware or logic processor resets during grid transients. Synchronics maintains firmware archives for major FACTS controller manufacturers, performs in-circuit reprogramming, and validates control loop stability on our test rig simulating real grid fault scenarios. We also repair associated PLCs and HMIs interfacing with FACTS systems.
Can you repair thyristor valve blocks and gate drivers for SVC systems?+
Yes. We specialize in SVC thyristor stack repair including thyristor replacement, gate drive optocoupler refurbishment, cooling circuit cleaning, and comprehensive thermal testing. Our engineers validate firing angle accuracy and reactive power response within ±2% before returning equipment. We handle both water-cooled and air-cooled valve configurations.
What is the typical turnaround time for FACTS controller repairs?+
Standard FACTS repairs take 5-7 working days. Complex gate drive and power module faults requiring component-level rework take 7-10 days. For critical power utility grid outages, we offer express service with diagnostics within 24 hours and priority repair scheduling. Emergency pickup and delivery available PAN India.
Do you provide FACTS harmonic filter and power quality module repairs?+
Absolutely. Synchronics repairs harmonic filter capacitor banks, tuning inductors, power quality monitoring devices, and data acquisition modules. We perform full impedance analysis, capacitor ripple current validation, and harmonic sweep testing to ensure compliance with grid codes and Indian electrical standards.
How do I send my FACTS 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 FACTS 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 FACTS 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 FACTS 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.
